摘要： An optical phased array comprises a first substrate layer, and a first device array on the first substrate layer. The first device array includes a first set of emitters and a first set of waveguides. Each waveguide in the first set of waveguides is respectively coupled to one of the emitters in the first set of emitters. A second substrate layer is over the first substrate layer in a stacked configuration, and a second device array is on the second substrate layer. The second device array includes a second set of emitters and a second set of waveguides. Each waveguide in the second set of waveguides is respectively coupled to one of the emitters in the second set of emitters. The second sets of emitters and waveguides are positioned on the second substrate to be offset with respect to the first sets of emitters and waveguides on the first substrate.

摘要： An optical coupler device comprises a substrate having a substantially planar upper surface, and a grating structure on the upper surface of the substrate. In one embodiment, the grating structure comprises a copropagating array of waveguides that are substantially parallel to each other and extend along at least a portion of the upper surface of the substrate. Each of the waveguides has opposing sidewalls, wherein a width of each waveguide is defined by a distance between the opposing sidewalls. The opposing sidewalls each have a periodic structure that produces a sidewall modulation for each of the waveguides. An input port is in optical communication with the grating structure. The input port is configured to direct an input light beam in plane into the grating structure such that the beam propagates along the waveguides. The grating structure is configured to diffract the beam out of plane and into free space.

摘要： This invention concerns an ultra-thin flat three-stage device comprised of a source (S), a gate (G), and a drain (D) waveguide building blocks. By transferring light sideways between different waveguides, the device is capable of delivering a 90-100% light extraction efficiency in conjunction with highly directional radiation patterns. The device can be very practical for light emission applications suffering from total internal reflection light trapping and diverging emission.
