    摘要： An optical phase detector circuit is provided that is suitable for use in an optical phase lock loop. The optical phase detector includes a first optical flip-flop circuit configured to produce a first digital output based on ON/OFF state of a first digital optical input and a digital electrical control signal. A second optical flip-flop circuit is configured to produce a second digital output based on ON/OFF state of a second digital optical input and the digital electrical control signal. An AND gate is operably coupled to both the first and second optical flip-flops. The AND gate produces the digital electrical control signal for supply to the first and second optical flip-flop circuits according to an AND function of the first and second digital outputs produced by the first and second optical flip-flop circuits.

    摘要： A method of forming an integrated circuit includes depositing a multilayer metal stack on at least one contact layer of semiconductor material. The multilayer metal stack includes a bottom interface layer formed by a combination of indium and at least one high temperature metal on the at least one contact layer of semiconductor material, at least one barrier layer formed on the bottom interface layer, and a layer formed from at least one high temperature metal on the at least one barrier layer. The metal stack is heated such that indium of the bottom interface layer forms a low resistance interface to contact layer. The at least one barrier layer functions as a barrier to diffusion of indium from the bottom interface layer. Subsequent to the heating, the resultant multilayer metal stack can be patterned to form at least one electrode for a given device of the integrated circuit.

    摘要： A semiconductor device that includes an optical resonator spaced from a waveguide structure to provide for evanescent-wave optical coupling therebetween. The optical resonator includes a closed loop waveguide defined by an epitaxial layer structure that includes at least one quantum well. The semiconductor device also includes circuitry configured to supply an electrical signal that flows within the epitaxial layer structure of the closed loop waveguide. The electrical signal affects charge density in at least quantum well of the closed loop waveguide and controls refractive index of the closed loop waveguide. In one embodiment, the electrical signal is a DC current signal that flows within a vertical thyristor structure of the closed loop waveguide to control refractive index of the closed loop waveguide such that resonance frequency of the closed loop waveguide corresponds to a characteristic wavelength of light.

    摘要： A photonic analog-to-digital converter is provided that includes a tunable light source, an optical sampling clock source, an optical splitter and a plurality of optical signal processing channels. The tunable light source produces an optical signal at a variable wavelength corresponding to analog levels of an electrical input signal. The optical sampling clock source produces an optical sampling clock signal that defines a sequence of sampling periods. The optical splitter is operably coupled to the tunable light source. The optical splitter splits the optical signal produced by the tunable light source for supply to the plurality of optical signal processing channels. Each one of the optical signal processing channels includes a photonic filter and corresponding optoelectronic thyristor comparator that is operably coupled to the optical sampling clock source. The optoelectronic thyristor comparator operates as a discriminator that generates a digital electrical signal representing whether the optical signal produced by the tunable light source has a wavelength that lies within a predetermined wavelength quantization level during the sampling periods defined by the optical sampling clock source. The photonic analog-to-digital converter further includes circuitry that generates a digital word corresponding to the digital electrical signals generated by the optoelectronic thyristor comparators of the plurality of optical signal processing channels.
