摘要： 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.

摘要： An electro-optic receiver includes a polarization splitter and rotator (PSR) that directs incoming light having a first polarization through a first end of an optical waveguide, and that rotates incoming light from a second polarization to the first polarization to create polarization-rotated light that is directed to a second end of the optical waveguide. The incoming light of the first polarization and the polarization-rotated light travel through the optical waveguide in opposite directions. A plurality of ring resonators is optically coupled the optical waveguide. Each ring resonator is configured to operate at a respective resonant wavelength, such that the incoming light of the first polarization having the respective resonant wavelength optically couples into said ring resonator in a first propagation direction, and such that the polarization-rotated light having the respective resonant wavelength optically couples into said ring resonator in a second propagation direction opposite the first propagation direction.

摘要： A ring resonator device includes a passive optical cavity having a circuitous configuration into which is built a photodetector device. The photodetector device includes a first implant region formed within the passive optical cavity that includes a first type of implanted doping material. The photodetector device includes a second implant region formed within the passive optical cavity that includes a second type of implanted doping material, where the second type of implanted doping material is different than the first type of implanted doping material. The photodetector device includes an intrinsic absorption region present within the passive optical cavity between the first implant region and the second implant region. A first electrical contact is electrically connected to the first implant region and to a detecting circuit. A second electrical contact is electrically connected to the second implant region and to the detecting circuit.

摘要： An optical data communication system includes an optical transmitter and an optical receiver. A polarization-maintaining optical data communication link extends from an optical output of the optical transmitter to an optical input of the optical receiver. The polarization-maintaining optical data communication link includes at least two sections of polarization-maintaining optical fiber optically connected through an optical connector. The at least two sections of polarization-maintaining optical fiber have different lengths. The optical connector is configured to optically align a fast polarization axis of a first polarization-maintaining optical fiber to a slow polarization axis of a second polarization-maintaining optical fiber. The optical connector is also configured to optically align a slow polarization axis of the first polarization-maintaining optical fiber to a fast polarization axis of the second polarization-maintaining optical fiber.

摘要： An optical input polarization management device includes a polarization splitter and rotator (PSR) that directs a portion of incoming light having a first polarization through a first optical waveguide (OW). The PSR rotates a portion of the incoming light having a second polarization to the first polarization so as to provide polarization-rotated light. The PSR directs the polarization-rotated light through a second OW. Light within the first and second OW's is input to a first two-by-two optical splitter (2x2OS). A first phase shifter (PS) is interfaced with either the first or second OW. Light is output from the first 2x2OS into a third OW and a fourth OW. Light within the third and fourth OW's is input to a second 2x2OS. A second PS is interfaced with either the third or fourth OW. Light is output from the second 2x2OS into a fifth OW for further processing.

摘要： A first portion of incoming light and a second portion of incoming light travel in opposite directions within a first optical waveguide. A ring resonator in-couples the first portion of incoming light and the second portion of incoming light from the first optical waveguide, such that the first portion of incoming light and the second portion of incoming light travel in opposite directions within the ring resonator. A second optical waveguide is disposed to in-couple the first portion of incoming light and the second portion of incoming light couple from the ring resonator, such that the first portion of incoming light and the second portion of incoming light travel in opposite directions within the second optical waveguide away from the ring resonator. One or more photodetector(s) are optically connected to receive the first portion of incoming light and the second portion of incoming light from the second optical waveguide.

摘要： An electro-optic combiner includes a polarization splitter and rotator (PSR) that directs a portion of incoming light having a first polarization through a first optical waveguide (OW). The PSR rotates a portion of the incoming light having a second polarization to the first polarization to provide polarization-rotated light. The PSR directs the polarization-rotated light through a second OW. Each of the first and second OW's has a respective combiner section. The first and second OW combiner sections extend parallel to each other and have opposite light propagation directions. A plurality of ring resonators is disposed between the combiner sections of the first and second OW's and within an evanescent optically coupling distance of both the first and second OW's. Each of ring resonators operates at a respective resonant wavelength to optically couple light from the combiner section of the first OW into the combiner section of the second OW.
