SILOXANE OPTICAL WAVEGUIDES

摘要

Optical waveguide structures containing siloxane resin composistions are core materials and a method for preparing the waveguides are disclosed. The siloxane resin compositions can be cured by thermal energy or actinic radiation. In addition, conventional patterning techniques can be used, which makes the present method ideal for practicing on a commerical scale. The optical waveguides of the invention exhibit very low optical losses and are compatible with silicon preocessing requirements, which makes them useful in integrated circuitry. In addition, the high refractive index contrasts between the siloxane resin core and various claddings, including other siloxane resins, makes the waveguides particularly desirable.
