    Abstract: An optical input/output chiplet is disposed on a first package substrate. The optical input/output chiplet includes one or more supply optical ports for receiving continuous wave light. The optical input/output chiplet includes one or more transmit optical ports through which modulated light is transmitted. The optical input/output chiplet includes one or more receive optical ports through which modulated light is received by the optical input/output chiplet. An optical power supply module is disposed on a second package substrate. The second package substrate is separate from the first package substrate. The optical power supply module includes one or more output optical ports through which continuous wave laser light is transmitted. A set of optical fibers optically connect the one or more output optical ports of the optical power supply module to the one or more supply optical ports of the optical input/output chiplet.

    Abstract: An interposer device includes a substrate that includes a laser source chip interface region, a silicon photonics chip interface region, an optical amplifier module interface region. A fiber-to-interposer connection region is formed within the substrate. A first group of optical conveyance structures is formed within the substrate to optically connect a laser source chip to a silicon photonics chip when the laser source chip and the silicon photonics chip are interfaced to the substrate. A second group of optical conveyance structures is formed within the substrate to optically connect the silicon photonics chip to an optical amplifier module when the silicon photonics chip and the optical amplifier module are interfaced to the substrate. A third group of optical conveyance structures is formed within the substrate to optically connect the optical amplifier module to the fiber-to-interposer connection region when the optical amplifier module is interfaced to the substrate.

    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: 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.

    Abstract: A remote memory system includes a substrate of a multi-chip package, an integrated circuit chip connected to the substrate, and an electro-optical chip connected to the substrate. The integrated circuit chip includes a high-bandwidth memory interface. An electrical interface of the electro-optical chip is electrically connected to the high-bandwidth memory interface. A photonic interface of the electro-optical chip is configured to optically connect with an optical link. The electro-optical chip includes at least one optical macro that converts outgoing electrical data signals received through the electrical interface from the high-bandwidth interface into outgoing optical data signals. The optical macro transmits the outgoing optical data signals through the photonic interface to the optical link. The optical macro also converts incoming optical data signals received through the photonic interface into incoming electrical data signals. The optical macro transmits the incoming electrical data signals through the electrical interface to the high-bandwidth memory interface.
