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: 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.

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.

Abstract: A first reflecting region is positioned at an end of an optical fiber and includes a polarization-sensitive reflector configured to selectively reflect a first polarization of light emanating from the optical fiber into a first reflected beam and transmit light that is not of the first polarization. The first reflected beam is directed toward a first optical grating coupler on a chip. A spacer layer is disposed on the first reflecting region such that light transmitted from the first reflecting region enters and passes through the spacer layer. A second reflecting region is disposed on the spacer layer and is configured to reflect light that is incident upon the second reflecting region into a second reflected beam directed toward a second optical grating coupler on the chip. A thickness of the spacer layer is set to control a separation distance between the first reflected beam and the second reflected beam.
