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.

Abstract: An optical coupler couples light from waveguides of a photonic integrated circuit (PIC) to output waveguides, for example waveguides of a planar lightwave circuit (PLC). The optical coupler includes optical elements having different optical properties. In some embodiments the optical properties vary to account for waveguide angled facets in the PIC, and in some embodiments the optical properties vary to account for the PIC being mounted at an angle compared to the PLC, or optical coupler.
