Abstract: Techniques and systems for a semiconductor laser, namely a grating-coupled surface-emitting (GCSE) comb laser, having thermal management for facilitating dissipation of heat, integrated thereon. The thermal management is structured in manner that prevents deformation or damage to the GCSE laser chips included in the semiconductor laser implementation. The disclosed thermal management elements integrated in the laser can include: heat sinks; support bars; solder joints; thermal interface material (TIM); silicon vias (TSV); and terminal conductive sheets. Support bars, for example, having the GCSE laser chip positioned between the bars and having a height that is higher than a thickness of the GCSE laser chip. Accordingly, the heat sink can be placed on top of the support bars such that heat is dissipated from the GCSE laser chip, and the heat sink is separated from directed contact with the GCSE laser chip due to the height of the support bars.

Abstract: Methods and systems support a dynamic ratio adjusting gearbox (DRAG) for communicating signals between at least one switch and a plurality of servers. The DRAG includes server interface ports, each coupled to a respective server. Each server interface port corresponds to a provisioned bandwidth, or the peak bandwidth allocated to the server interface port. The DRAG includes a switch interface port, coupled to a respective switch. The switch interface port corresponds to a provided bandwidth, which is the peak amount of bandwidth supported by the switch. The DRAG can dynamically allocate an amount of provisioned bandwidth for each server interface port such that an aggregate amount of provisioned bandwidth does not exceed an aggregate amount of bandwidth from the at least one switch coupled to the DRAG, and based on an amount of bandwidth utilized in operation, thereby improving bandwidth utilization and mitigating stranded bandwidth.

Abstract: An photonic circuit includes a substrate, a plurality of first light waveguides disposed on the substrate, the first light waveguides extending in a first direction, a plurality of second light waveguides disposed on the substrate and extending in a second direction intersecting the first direction, and a plurality of first micro-ring resonators disposed on the substrate. Each of the first light waveguides has an intersection with each of the second light waveguides. Each of the intersections is provided with a first micro-ring resonator of the first micro-ring resonators. Each first micro-ring resonator is configured to route signals of a respective wavelength from one of the light waveguides at the intersection to another light waveguide at the intersection.

Abstract: Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. The pluggable optical transceiver modules include an on-board application-specific integrated circuit (ASIC), optical transceiver, and an optical socket allowing a fiber to connect to the optical transceiver. Pluggable optical transceiver modules implement an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in manner that does not require the fiber jumper, while ensuring tight alignment tolerances. In some embodiments, optical transceiver modules are designed to achieve a direct opt-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, an adaptor is distinctly designed, directly connecting an external cable to the optical socket (eliminating the use of fiber jumper and faceplate connector in the module). In some embodiments, a rigid body opto-mechanical interface is used.

Abstract: A photonic node includes a first circuit disposed on a first substrate and a second circuit disposed on a second substrate different from the first substrate. The first circuit is configured to route light signals originated from the photonic node to local nodes of a local group in which the photonic node is a member. The second circuit is configured to route light signals received from a node of an external group in which the photonic node is not a member, to one of the local nodes.

Abstract: Waveguide shuffle blocks (WSBs) are provided that may incorporate waveguides routed in any pattern to effectuate many-to-many connectivity between optical cables/fibers or other WSBs connected thereto. Such WSBs may be configured in ways that allow the WSBs to be stacked and to achieve effective optical cable/fiber organization. Moreover, such WSBs may include readable tags that can provide information regarding a particular WSB configuration and/or what optical cables/fibers are connected so that network topology can be discovered and monitored. Some WSBs may be configured as wavelength shifting shuffles (WSSs) that allow a particular wavelength(s) of an optical signal(s) to be routed as desired and/or alter a first wavelength associated with a particular optical signal to a second wavelength. In other embodiments WSSs can be configured to allow for wavelength multiplexing/demultiplexing.
