Abstract:
A hybrid active electronic and optical Fabry-Perot cavity integrated in a Silicon-On-Insulator (SOI) wafer, the SOI wafer including a thin silicon film, the hybrid active electronic and optical Fabry-Perot cavity comprising:a waveguide formed in the thin silicon film, the waveguide configured to receive light; an active electronic circuit positioned within the waveguide, wherein a flow of light through the waveguide can be altered depending on a state of the active electronic circuit; a first series of waveguide gratings located relative to the waveguide, each adjacent one of said first series of waveguide gratings spaced by a prescribed spacing; and a second series of waveguide gratings located relative to the waveguide, each adjacent one of said second series of waveguide gratings spaced by the prescribed spacing.
