OPTOELECTRONIC DEVICES AND METHODS OF FABRICATING SAME

摘要

A hybrid graphene-silicon optical cavity for chip-scale optoelectronics having attributes including resonant optical bistability for photonic logic gates and memories at femtojoule level switching per bit, temporal regenerative oscillations for self-pulsation generation at record femtojoule cavity circulating powers, and graphene-cavity enhanced four-wave mixing at femtojoule energies on the chip.

主权项

1. A photonic crystal comprising:
a body formed at least from a silicon material, the body having opposing top and bottom surfaces; a plurality of cavities disposed on the body, at least some of the cavities defining an opening extending through at least one of the top and bottom surfaces; and a layer of graphene disposed on at least one surface of the body.
