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 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.

Abstract: A beam steering structure includes an alignment structure shaped to receive and align an optical fiber such that an axis of a core of the optical fiber is oriented in a first direction. The beam steering structure includes an end portion having an angled optical surface oriented at a non-zero angle relative to the first direction. The end portion is shaped and positioned so that light propagating along the first direction from the optical fiber passes through the end portion to reach the angled optical surface. A reflecting system is positioned on the angled optical surface across the first direction. The reflecting system is configured to reflect incident light propagating along the first direction into a first reflected beam of a first polarization and a second reflected beam of a second polarization. The first and second reflected beams are directed into first and second optical communication channels, respectively.

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 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 photonic system includes a passive optical cavity and an optical waveguide. The passive optical cavity has a preferred radial mode for light propagation within the passive optical cavity. The preferred radial mode has a unique light propagation constant within the passive optical cavity. The optical waveguide is configured to extend past the passive optical cavity such that at least some light propagating through the optical waveguide will evanescently couple into the passive optical cavity. The passive optical cavity and the optical waveguide are collectively configured such that a light propagation constant of the optical waveguide substantially matches the unique light propagation constant of the preferred radial mode within the passive optical cavity.

Abstract: A computer memory system includes an electro-optical chip, an electrical fanout chip electrically connected to an electrical interface of the electro-optical chip, and at least one dual in-line memory module (DIMM) slot electrically connected to the electrical fanout chip. A photonic interface of the electro-optical chip is optically connected to an optical link. The electro-optical chip includes at least one optical macro that converts outgoing electrical data signals into outgoing optical data signals for transmission through the optical link. The optical macro also converts incoming optical data signals from the optical link into incoming electrical data signals and transmits the incoming electrical data signals to the electrical fanout chip. The electrical fanout chip directs bi-directional electrical data communication between the electro-optical chip and a dynamic random access memory (DRAM) DIMM corresponding to the at least one DIMM slot.
