    Abstract: 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.

    Abstract: One example includes an optical modulation system. The system includes a waveguide system comprising a waveguide to propagate an optical signal therethrough. The waveguide system further includes a grating separated from the waveguide via a cavity. The system further includes an optical coupling controller to selectively move a fluid with respect to the cavity in response to a control signal. The fluid can be moved with respect to the cavity from a first state to a second state to couple the optical signal to the grating to cause a portion of the optical signal to be diffractively redirected via the grating.

    Abstract: An optical coupling system includes an optical signal source to provide an optical signal from an aperture. The system also includes a substantially planar high-contrast grating (HCG) lens to convert an optical mode of the optical signal to provide a converted optical signal having a mode-isolating intensity profile. The system further includes an optical element to receive the converted optical signal. The optical signal source and the substantially planar HCG lens can be arranged to substantially mitigate coupling of a reflected optical signal associated with the converted optical signal that is reflected from the optical element to the aperture of the optical signal source based on a reflected mode-isolating intensity profile.
