Abstract:
An integrated circuit comprising:a monocrystalline silicon substrate; a monocrystalline perovskite oxide material overlying at least a portion of the monocrystalline silicon substrate; an amorphous oxide material located between the monocrystalline perovskite oxide material and the monocrystalline silicon substrate; a monocrystalline compound semiconductor material overlying at least a portion of the monocrystalline perovskite oxide material; a plurality of electrical circuits each having at least one input operable to receive an electrical signal, at least one of said electrical circuits comprising a transistor; a waveguide operable to propagate an optical signal selected from the group consisting of an optical data signal, an optical clock signal, and an optical control signal; and a photodetector operable to convert the optical signal to an electrical signal, said photodetector having an input coupled to said waveguide and an output coupled to an input of at least one of said plurality of electrical circuits, wherein at least a portion of at least one of said plurality of electrical circuits is formed within said monocrystalline silicon substrate.
