    摘要： Planar, polarization insensitive, optical elements to control refraction of transmitted light in free space are disclosed. In one aspect, an optical element includes a substrate having a planar surface, and a polarization insensitive, high contrast, sub-wavelength grating composed of posts that extend from the planar surface. The grating has at least one region. Within each region, cross-sectional dimensions of the posts and/or lattice arrangement of the posts are nonperiodically varied to control refraction of light transmitted through the optical element.

    摘要： Embodiments of the present invention are directed to optical waveguide-to-fiber interconnects. In one aspect, an optical fiber-to-waveguide interconnect includes a grating coupler (102) located at the end of a waveguide, and a grating layer (110) disposed on the end of an optical fiber (112). The optical fiber includes a core (118) and the grating layer includes a planar, non-periodic, sub-wavelength grating (116). Light carried by the waveguide into the grating coupler is output and coupled into the core via the sub-wavelength grating, and light transmitted along the core to the grating layer is directed by the sub-wavelength grating into the grating coupler for transmission in the waveguide.

    摘要： Tunable resonator systems and methods for tuning resonator systems are disclosed. In one aspect, a resonator system includes an array of resonators disposed adjacent to a waveguide, at least one temperature sensor located adjacent to the array of resonators, and a resonator control electronically connected to the at least one temperature sensor. Each resonator has a resonance frequency in a resonator frequency comb and channels with frequencies in a channel frequency comb are transmitted in the waveguide. Resonance frequencies in the resonator frequency comb are to be adjusted in response to ambient temperature changes detected by the at least one temperature sensors to align the resonance frequency comb with the channel frequency comb.

    摘要： A quantum device includes a resonator and a tuning structure. The tuning structure is made a material such as a chalcogenide and is positioned to interact with the electromagnetic radiation in the resonator so that a resonant mode of the first resonator depends on a characteristic of the tuning structure. The resonator is optically coupled so that a transition between quantum states associated with a defect produces electromagnetic radiation in the resonator. The characteristic of the tuning structure is adjustable after fabrication of the resonator and the tuning structure.
