摘要： An optical coupling system and method of fabrication are included. The optical coupling system includes a substrate layer and an optical waveguide material overlying the substrate layer. The optical waveguide material can include a grating. The system also includes a cover material overlying the optical waveguide material to couple an optical signal to the optical waveguide material via the grating at a coupling angle. Approximately zero energy of the coupled optical signal is lost in the substrate layer due to a combination of the coupling angle and a difference in refractive indices between the cover material and the substrate layer.

摘要： A system includes a non-uniform grating (100) having a first region (110) with a first refractive index and second regions (120) with a second refractive index. A pattern of the second regions (120) varies with an angular coordinate such that phase shifts of an incident beam (130) created by the grating (100) cause destructive interference that creates an intensity minimum within an output beam (134) from the grating (100).

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.
