Abstract: A thermo-optic phase shifter includes a substrate having a cavity formed into an upper region of the substrate. The thermo-optic phase shifter includes an optical waveguide disposed above the substrate. The optical waveguide extends across and above the cavity. The thermo-optic phase shifter also includes a heater device disposed along a lateral side of the optical waveguide. The heater device extends across and above the cavity. The cavity is formed by an undercut etching process after the optical waveguide and the heater device is formed. The optical waveguide can be formed to include one or more segments that pass over the cavity. Also, a second heater device can be included such that the one or more segments of the optical waveguide that extend over the cavity are bracketed by heater devices. Thermal transmission structures can be included to enhance heat transfer between the heater device(s) and the optical waveguide.

Abstract: An optical distribution network includes a fore-positioned optical multiplexer section that has a plurality of optical inputs and a plurality of intermediate optical outputs. Each of the plurality of optical inputs of the fore-positioned optical multiplexer section receives a respective one of a plurality of input light signals of different wavelengths. The fore-positioned optical multiplexer section multiplexes a unique subset of the plurality of input light signals onto each of the plurality of intermediate optical outputs. The optical distribution network also includes an optical coupler section that has a plurality of optical inputs respectively optically connected to the plurality of intermediate optical outputs of the fore-positioned optical multiplexer section. The optical coupler section distributes a portion of each light signal received at each of the plurality of optical inputs of the optical coupler section to each and every one of a plurality of optical outputs of the optical coupler section.
