December 6, 2005: 2005 Holiday Lecture "Put some Spark in your Holidays" by Prof. Ken Pedrotti, UC Santa Cruz Baskin School of Engineering

Abstract: In 2003 it was proposed by Dr. Tony Siegman to hold a series of "Christmas Lectures" humbly modeled after the popular Faraday Lectures of the Royal Society of London. It is in this spirit that we invite you and your families to this wonderful annual tradition.

The early and fascinating history of radio spawned what we know today as the electronics industry. This story will be told via live working demonstrations of early spark-gap apparatus inspired by Tesla, Oliver Lodge's important but forgotten syntonic spark system, numerous radio relics. The story then leads us full circle to the ultra wide band radio systems proposed for the future, throwbacks to the distant past, and on to a glimpse of what the future might hold.

November 1, 2005: "Solid State Light Sources: Addressing the Barriers that Limit Their Application to General Illumination" by Steve Johnson, Lawrence Berkeley National Laboratory

Abstract: The potential of LEDs and OLEDs as light sources for general illumination will be discussed relative the technical barriers that must be overcome before these sources can replace the ubiquitous incandescent and fluorescent light sources we use daily. Of the two sources, LEDs have the greatest near term opportunity, hence the presentation will focus more on this source. The discussion will start at the LED die level and progress through the development of a lighting system, addressing the issues of extraction efficiency, thermal management and optical control. LEDs are a wonderful point source for lighting applications, where OLEDs are a much larger diffuse source. This major difference in optical performance makes the two technologies complementary rather than competitive. OLEDs are being aggressively developed for the display market and it is expected this will have a synergistic effect in speeding their development as a light source. The technical barriers for OLEDs of lif! etime, encapsulation, and extraction efficiency will again be discussed briefly in context of developing a lighting system.

Bio: Dr. Steve Johnson is Group Leader for the Lighting Research Group at Lawrence Berkeley National Laboratory in Berkeley, California. The Lighting Research Group performs research into light sources and ballasts, lighting controls, light distribution systems, and human factors. Research at LBNL is principally focused on technologies that will improve the efficiency of current practice for both residential and commercial applications of lighting. Since joining LBNL in 1996, Dr. Johnson has shifted the emphasis in light source development at the laboratory from discharge lamps to solid state devices. He directs research in the area of both LEDs and OLEDs. Prior to joining LBNL, Dr. Johnson spent 20 years working in the lighting industry.

July 12, 2005: "Temporal Imaging: Making A Many-Colored Processing Engine: Signal Processing with Optical Filters" by Christi Madsen, TAMU, College Station, TX

Abstract: The ultimate information capacity of optical fibers is far beyond currently deployed systems even with the exponential growth in system capacity over the past 20 years. Even now, the performance of high-capacity, long-distance wavelength-division-multiplexed (WDM) networks depends significantly on reconfigurable optical filters for bandwidth management and adaptive filters for compensating analog impairments. Optical filters are also key elements in optical code generation and detection with applications in optical packet header processing. Whether the end goal is for communications or high-speed signal processing, optical filters that can operate on amplitude, phase and polarization are critical to unleashing the full potential of optical systems. To be practical, a cost-effective implementa! tion that can scale in optical circuit integration density and functionality is required. This talk addresses optical filters in the ! context of their analog and digital relatives. I will show how well-known filter types are related to the underlying interference mechanisms and how digital filter theory concepts are beneficially translated to the optical domain. Then, the present capabilities of integrated optics for implementing adaptive optical filters and an overview of some challenges ahead will be discussed. Adaptive filters implemented using high-index-contrast silica-on-silicon planar waveguides with applications to tunable chromatic dispersion compensation and polarization monitoring, control and polarization mode dispersion compensation will be! used as examples. With state-of-the-art integrated optical filters, we have the ability to realize a many-colored, high-speed and cost-effective processing engine that truly harnesses the power of photonics.

She joined AT&T Bell Laboratories in 1987 and worked for the submarine systems business unit. After completing her Ph.D, she transferred to the integrated photonics research department at Bell Laboratories. Since then, her research has focused on the application of digital filter and signal processing techniques to optical filters for high-speed, high-capacity optical communication systems. In 1998, Madsen invented a class of tunable, multi-stage optical allpass filters that allow any phase response to be approximated and have application in chromatic dispersion compensation and polarization mode dispersion compensation. She has given a short course on "Optical Filters for WDM Systems: Theory, Technologies, and Applications" at OFC and is the 2004 General Chair for the Integrated Photonics Research (IPR) Conference.

June 07, 2005: "Temporal Imaging: Ultrafast Optical Waveform Manipulation and Recording" by Corey Bennett, LLNL

Abstract: There exists a duality between the physical components of imaging systems in space and processes which can occur in the time domain. Equations describing paraxial diffraction of a beam of light and that describing narrow band dispersion of a pulse in a dispersive media have the same mathematical form and thus can perform a similar role. A conventional lens in space imparts a quadratic spatial phase profile and there are a variety of ways to impart a quadratic temporal phase profile. Such a device acts as a time lens. Cascading dispersion, a 'time lens', and further dispersion, in the proper balance, it is possible to build a system that behaves in the time domain the way an imaging system does in space. Arbitrary waveforms can be expanded, compressed, and even Fourier transformed, in real time, with ultrafast resolution (< ps). The fundamental principles of temporal imaging systems will be reviewed along with a summary of past work which demonstrated 100x magnification of an optical waveform with 200 fs resolution. Current efforts in developing a new class of long record length, ultrafast resolution, recording systems based on temporal imaging will be reviewed.

Bio: Dr. Corey V. Bennett is an Engineer with the Electronics Engineering Division at Lawrence Livermore National Laboratory (LLNL), where he currently works on a variety of high speed photonics projects. These include the development of a new class of radiation detectors which produce a modulated optical carrier, next generation optical communications systems based on Optical Code Division Multiple Access (O-CDMA), and a new ultrafast single-shot transient recorder based on Temporal Imaging. Corey received his M.S. in Electrical Engineering from UCLA in 1995. In 1998 he joined LLNL where he completed his Ph.D. research in Parametric Temporal Imaging and Aberration Analysis through collaboration between Prof. Brian Kolner's research group and the LLNL Photonics Group headed by Mark Lowry. At LLNL he demonstrated a temporal microscope system, achieving 103x temporal magnification of an ultrafast waveform with a total system resolution better than 200 fs. After completing his Ph.D. in 2000 he joined Terawave Communications were he worked on fiber optic communication systems for the optical access market. Projects included the development of point-to-point DWDM links at 2.488 Gbps and a 622 Mbps burst mode transmitter and continuous receiver module, both for use in a passive optical networking tree architecture. Corey returned to LLNL in early 2002. He's returned to his work on ultrafast diagnostics technologies as well as working on new optical communication systems.


May 03, 2005: "Combining Light with Motion: Hybrid Integration of Light Emitters and Detectors with SOI based MOEMS Systems" by Dr. Joel Kubby, UC Santa Cruz

Abstract: A multidisciplinary team of end users and suppliers (Maxim Integrated Products, Microcosm Technologies, Microscan Systems, Optical Micro-Machines, Standard MEMS and Xerox) have combined to develop a novel yet broadly enabling process for the design, fabrication and assembly of Micro-Opto-Electro-Mechanical Systems (MOEMS). A key goal is to overcome the shortcomings of the polysilicon layer used for fabricating optical components in a conventional surface micromachining process. These shortcomings include the controllability and uniformity of material stress that is a major cause of curvature and deformation in suspended microstructures. The approach taken by the consortium to overcome these issues is the use of the single-crystal-silicon device layer of a silicon-on-insulator (SOI) wafer for the primary structural layer for MOEMS devices. Since optical flatness and mechanical reliability are of utmost importance in the realization of such devices, the use of the silicon device layer is seen as an excellent choice for devices which rely on the optical integrity of the materials used in their construction. A three-layer polysilicon process consisting of two structural layers is integrated on top of the silicon device layer. This allows for the formation of sliders, hinges, torsional springs, comb drives and other actuating mechanisms for positioning and movement of the optical components. Flip-chip bonding techniques are also being developed for the placement of edge and surface emitting lasers on the front and back surfaces of the silicon wafer, adding to the functionality and broadly enabling nature of this process.

Bio: Joel Kubby is an Associate Professor in the Department of Electrical Engineering at the University of California at Santa Cruz. His research is in the area of Micro-Electro-Mechanical Systems (MEMS). He works closely with the NSF Center for Adaptive Optics at UC Santa Cruz for applications of optical MEMS in astronomy and vision sciences. Prior to joining the faculty at UCSC in January 2005, he was a technical manager in the Xerox Wilson Center for Research and Technology in Rochester, New York, where he led a research group working on the applications of MEMS technology for printing. He has over 50 patents in the design, fabrication and applications of fluidic and optical MEMS, and is a registered patent agent with the United States Patent and Trademark Office.


April 05, 2005: "Semiconductor Ultraviolet Optical Sources: Status, Challenges, and Applications" by Dr. Noble Johnson, Palo Alto Research Center

Abstract: Over the past 40 years semiconductor optical sources, light emitting diodes (LEDs) and laser diodes (LDs), have been displacing conventional light sources and gaseous lasers in commercial applications throughout the near infrared (IR) and visible regions of the spectrum. And in many cases, newer semiconductor sources with improved performance have displaced older semiconductor sources; an example currently in progress is the replacement of red LDs in DVDs by violet LDs for the next generation Blue-Ray or HD-DVD format.

The new frontier in the development of semiconductor sources is the ultraviolet (UV). This effort is well underway, with LDs already demonstrated in the AlGaInN materials system down to 340 nm and LEDs operating below 280 nm. Such UV sources will enable miniaturization and/or cost/performance improvements for existing UV-based systems, with proliferation of existing functionality and realization of new applications. In comparison with existing UV gas sources (lasers and lamps) and other more complex and costly solid-state lasers (e.g., photo-pumped lasers and frequency-tripled /quadrupled lasers), semiconductor UV sources offer several advantages including compactness, low power consumption, low cost, and long lifetimes. These features will drive a host of commercial applications in areas that include biotechnology, water purification, and UV curing. The first area of commercialization will likely be replacement of Hg lamps for germicidal and (low-power) UV curing applications. In addition, as with any truly destabilizing technology, there will likely be completely new applications that have yet to be conceived.

Bio: Dr. Noble Johnson received his Ph.D. degree from Princeton University in 1974 under a National Defense Graduate Fellowship. From 1974 to 1976 he worked at SRI International (Menlo Park, CA) in the Radiation Physics Group of the Physical Sciences Division.

January 12, 2005: Joint meeting with SCV-CPMT "Optical Fiber Coatings: The State-of-the-Art and the Application of a New Nano-material" by Dr. Ephraim Suhir

Abstract: This review addresses the state-of-the-art of the mechanics of coated optical fibers. We discuss various mechanical problems in the analysis, design and reliability evaluations of polymer-coated or metallized optical fibers, including predictive modeling (mostly analytical), mechanical behavior of hermetic and non-hermetic coatings, adhesion and strippability problems, etc. The review is based primarily on the author's research conducted during his almost twenty-year tenure with Bell Laboratories, Basic Research, Murray Hill, New Jersey. The extension part concerns the application of a newly developed nanoparticle material (NPM) as an attractive substitute for the existing optical fiber coatings. The improvement over the existing knowledge-base is two-fold: 1) understanding of the role, objectives, challenges and approaches of structural mechanics in the design and reliability evaluations of coated optical fibers and fiber coatings; and 2) development (invention) of a new nano-particle material as an attractive substitute for the existing optical fiber coatings and, in some cases, of claddings as well. Some additional applications of the NPM are also addressed and briefly discussed.
