摘要： Wavefront synthesizers and optical switches implemented with wavefront synthesizers are disclosed. In one aspect, a wavefront synthesizer (100,200) includes a waveguide tree (102,202) composed a root waveguide that branches into at least two terminus waveguides. The root waveguide is integrated with a source (122) to inject light into the waveguide tree via the root waveguide. The synthesizer includes output couplers (108-111,212-219) 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 (104-107,204-211) 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.
