Patent ID: 8718480

Claim:
An optical communication system comprising of a silicon based light emitting device operating by means of avalanche carrier multiplication and emitting at the below threshold wavelength detection range for Silicon of 850 nm; a low loss optical waveguide operating in the below threshold wavelength detection range for Silicon of 850 nm being fabricated at the interface of a silicon and metal oxide over-layers; and an optical detector, wherein a complete and all-silicon optical communication system is formed being capable of transferring electrical signals in terms of optical intensity variations, such intensities then being propagated through the waveguide and being detected by the optical detector; and being converted back to electrical signals, whereby the optical waveguide is formed at the interface of the silicon substrate and the silicon over-layers by using a combination of shallow and deep trench realizations and depositing silicon oxide and silicon nitride or any other suitable refractive materials into the trench regions.
