摘要： A system can include a transmitter that produces an optical signal having a plurality of carrier frequencies and a receiver separated from the transmitter by free space through which the optical signal propagates. The receiver includes an array of detectors of multiple types, with the types being capable of detecting light respectively having the carrier frequencies. A location of an incident area where the optical signal is incident on the detector array generally depends on a misalignment of the receiver relative to the transmitter, but the detectors in the detector array are arranged so that at least one detector of each of the types detects light from the optical signal regardless of where the incident area is on the detector array.

摘要： Wavefront synthesizers and optical switches implemented with wavefront synthesizers are disclosed. In one aspect, a wavefront synthesizer includes a waveguide tree composed a root waveguide that branches into at least two terminus waveguides. The root waveguide is integrated with a source to inject light into the waveguide tree via the root waveguide. The synthesizer includes output couplers located at the ends of the terminus waveguides. Each output coupler outputs a wavefront associated with a portion of the light injected with at least two of the wavefronts overlapping to form at least one beam of light via constructive interference. The synthesizer also includes microring resonators disposed adjacent to the terminus waveguides. Each microring is independently tunable to apply a phase shift in the wavefront output from one of the output couplers to steer the direction of the beam and the at least two wavefronts.
