  • Patent number: 11876345
    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.

  • Patent number: 11415763
    Abstract: Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. Pluggable optical transceiver modules implement a rigid-plane jumper that provides an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in a manner that does not require the fiber jumper, while ensuring reduced optical loss. In some embodiments one or more rigid waveguide plates act as an opto-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, the rigid waveguide plates are coupled to a faceplate connector, and a CWDM block that is in turn optically coupled to the optical socket. In some embodiments, the CWDM block is directly attached to the rigid waveguide plates. In some embodiments, the CWDM block is indirectly attached to the rigid waveguide plates using a half periscope.

  • Patent number: 11391898
    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).
