| Abstract: Silicon-based optoelectronics is a wide-ranging field, whose aim is to capitalise on the availability of low-cost, reliable, high performance silicon electronics to provide high capacity optical components in an effective manner. In this paper some of the recent progress in the development of silicon-based optical waveguides will be discussed, leading to the conclusion that silicon should be a material of choice for reliable, cost-effective devices. Perhaps the most mature technology is based on silicon-on-insulator (SOI) materials. These materials have the advantage of compatibility with standard CMOS processing. Complex SOI-based photonic circuitry is now available. The use of silicon-based alloys, in particular Silicon-Germanium, allows the optical properties of the waveguide layer to be tailored thus providing additional flexibility in design. The use of such alloys can either be adopted within an epitaxial layer grown on a SOI structure or directly on to a silicon substrate. Finally, the use of porous silicon for providing optical waveguides will be examined. Porous silicon provides much flexibility to the waveguide designer, including the capacity to dope with rare-earth materials such as erbium as a step towards optical amplification. |
