摘要： A method of operating an optical isolator having first and second optical splitter-combiners disposed within a semiconductor die. The optical splitter-combiners are coupled together into an interferometer configuration by first and second waveguide sections also disposed in the semiconductor die. A non-reciprocal optical phase shift element is disposed within the semiconductor die. The method operates by splitting forward and backward propagating optical waves into first and second portions propagating along first and second waveguide sections of a waveguide structure disposed within a semiconductor die, injecting first and second charge carriers having opposite spin polarizations into the first waveguide section; constructively recombining the first and second portions of the forward propagating optical wave, and destructively recombining the first and second portions of the reverse propagating optical wave

摘要： An integrated optical circuit includes waveguides formed in the integrated optical circuit. One set of waveguides is a set of optical amplifiers doped with rare earth ions. A second set of waveguides is a multiplexer or demultiplexer, such as an arrayed waveguide grating (AWG). The set of optical amplifiers and the AWG are coupled together via waveguides formed in the integrated optical circuit. Other elements on the integrated optical circuit are coupled to the set of optical amplifiers and the AWG via optical fibers. The spectral response of the AWG is modified to compensate for the spectral gain of the AWG. The lengths of the individual optical amplifiers in the set of optical amplifiers may be varied to cause uniform power distribution across channels. The integrated optical circuit also has a pump coupler to couple a pump source to the set of optical amplifiers.

摘要： Interface loss, diffraction loss, and physical sizes of arrayed-waveguide (AWG) devices, such as AWG routers, are reduced via use of an array of asymmetric waveguide couplers that is inserted between arrayed waveguides. The asymmetric waveguide couplers operate to couple leaked optical power back to the arrayed waveguides. A lenslet matrix may also be used to pre-channel portions of an optical wavefront. The lenslet matrix includes lenslet columns that are aligned with gaps between the arrayed waveguides, such that the portions of the optical wavefront are directed towards the arrayed waveguides rather than towards the gaps.
