  • STACKED TRANSCEIVER ARCHITECTURE
    Publication number: 20210349272
    Abstract: An optical transceiver may include a circuit board, lasers, and a PLC including optical multiplexers and demultiplexers. The PLC may be coupled to fiber optic lines at a forward edge of the PLC, with a rear edge of the PLC receiving light for transmission generated by the lasers. Light received at the forward edge of the PLC may be demultiplexed into data channels and routed to a top surface of the PLC for optoelectronic conversion by photodetectors. In some embodiments each data channel is routed into a corresponding plurality of waveguides, with each of the corresponding plurality of waveguides providing light to the same photodetector. In some embodiments at least some receive side electronic circuitry, other than photodetectors, is stacked on top of the PLC.

  • Optical module for terabit switch
    Patent number: 10782472
    Abstract: A switch module includes a switch integrated circuit (IC), a photonic integrated circuit (PIC), and a planar lightwave circuit (PLC). The PIC may include a plurality of light sources, an optical splitter, and a plurality of modulators. A dual MEMS may be used to align lens arrays, which may be used to couple light from the PIC to the PLC.
