Abstract: A laser light generator is configured to generate one or more wavelengths of continuous wave laser light. The laser light generator is configured to collectively and simultaneously transmit each of the wavelengths of continuous wave laser light through an optical output of the laser light generator as a laser light supply. An optical fiber is connected to receive the laser light supply from the optical output of the laser light generator. An optical distribution network has an optical input connected to receive the laser light supply from the optical fiber. The optical distribution network is configured to transmit the laser light supply to each of one or more optical transceivers and/or optical sensors. The laser light generator is physically separate from each of the one or more optical transceivers and/or optical sensors.

Abstract: A TORminator module is disposed with a switch linecard of a rack. The TORminator module receives downlink electrical data signals from a rack switch. The TORminator module translates the downlink electrical data signals into downlink optical data signals. The TORminator module transmits multiple subsets of the downlink optical data signals through optical fibers to respective SmartDistributor modules disposed in respective racks. Each SmartDistributor module receives multiple downlink optical data signals through a single optical fiber from the TORminator module. The SmartDistributor module demultiplexes the multiple downlink optical data signals and distributes them to respective servers. The SmartDistributor module receives multiple uplink optical data signals from multiple servers and multiplexes them onto a single optical fiber for transmission to the TORminator module. The TORminator module coverts the multiple uplink optical data signals to multiple uplink electrical data signals, and transmits the multiple uplink electrical data signals to the rack switch.

Abstract: A photoresist material is deposited, patterned, and developed on a backside of a wafer to expose specific regions on the backside of chips for etching. These specific regions are etched to form etched regions through the backside of the chips to a specified depth within the chips. The specified depth may correspond to an etch stop material. Etching of the backside of the wafer can also be done along the chip kerf regions to reduce stress during singulation/dicing of individual chips from the wafer. Etching of the backside of the chips can be done with the chips still part of the intact wafer. Or, the wafer having the pattered and developed photoresist on its backside can be singulated/diced before etching through the backside of the individual chips. The etched region(s) formed through the backside of a chip can be used for attachment of optical component(s) to the chip.

Abstract: 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.

Abstract: 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.

Abstract: 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 (2×2OS). A first phase shifter (PS) is interfaced with either the first or second OW. Light is output from the first 2×2OS into a third OW and a fourth OW. Light within the third and fourth OW's is input to a second 2×2OS. A second PS is interfaced with either the third or fourth OW. Light is output from the second 2×2OS into a fifth OW for further processing.

Abstract: A laser module includes a laser source and an optical marshalling module. The laser source is configured to generate and output a plurality of laser beams. The plurality of laser beams have different wavelengths relative to each other. The different wavelengths are distinguishable to an optical data communication system. The optical marshalling module is configured to receive the plurality of laser beams from the laser source and distribute a portion of each of the plurality of laser beams to each of a plurality of optical output ports of the optical marshalling module, such that all of the different wavelengths of the plurality of laser beams are provided to each of the plurality of optical output ports of the optical marshalling module. An optical amplifying module can be included to amplify laser light output from the optical marshalling module and provide the amplified laser light as output from the laser module.
