In one aspect, an optical isolator includes a Faraday crystal with a first surface and a second surface opposite the first surface, a first one-dimensional sub-wavelength grating disposed on the first surface, and a second one-dimensional sub-wavelength grating disposed on the second surface. The isolator is to receive a first input beam of light on the first grating and output a polarized first output beam of light through the second grating approximately parallel to the first input beam. The isolator is to also receive a second input beam of light on the second grating and output a polarized second output beam of light through the first grating with the second output beam offset from the second input beam.

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.
