The present invention provides a silicone composition that includes an epoxy-functional organopolysiloxane resin and an epoxy-functional organosiloxane oligomer, and a method of preparing optical waveguides using the silicon composition. The present invention also provides a cured silicon composition, and an optical waveguide that includes the cured silicon composition.

Epoxy-functional radiation-curable composition containing an epoxy-functional siloxane oligomer for enhanced film retention and adhesion during solvent development

A light guide has a transmission of greater than 90 percent, a refractive index greater than 1.4, and less than 10 haze percent. The light guide also includes an organosiloxane block copolymer having a weight average molecular weight of at least 20,000 g/mole. The organosiloxane block copolymer includes 40 to 90 mole percent disiloxy units of the formula [RSiO] arranged in linear blocks each having an average of from 10 to 400 disiloxy units [RSiO] per linear block, 10 to 60 mole percent trisiloxy units of the formula [RSiO] arranged in non-linear blocks each having a weight average molecular weight of at least 500 g/mol, and 0.5 to 25 mole percent silanol groups [&#x2261;SiOH]. Ris independently a Cto Chydrocarbyl and Ris independently a Cto Chydrocarbyl. Moreover, at least 30% of the non-linear blocks are crosslinked with another non-linear block and aggregated in nano-domains.

The present invention provides a method and apparatus for random number generation using a scattering waveguide. The apparatus includes a light source for providing coherent light and a scattering waveguide for receiving the coherent light and providing scattered light. The relative position of the light source and the scattering waveguide are variable. The apparatus also includes a detector for forming at least one random number based on the scattered light.
