    Abstract: Consistent with the present disclosure, a photonic integrated circuit (PIC) is provided that has 2 N channels (N being an integer). The PIC is optically coupled to N optical fibers, such that each of N polarization multiplexed optical signals are transmitted over a respective one of the N optical fibers. In another example, each of the N optical fibers supply a respective one of N polarization multiplexed optical signals to the PIC for coherent detection and processing. A multiplexer and demultiplexer may be omitted from the PIC, such that the optical signals are not combined on the PIC. As a result, the transmitted and received optical signals incur less loss and amplified spontaneous emission (ASE) noise. In addition, optical taps may be more readily employed on the PIC to measure outputs of the lasers, such as widely tunable lasers (WTLs), without crossing waveguides.

    Abstract: A device may include a substrate. The device may include a carrier mounted to the substrate. The device may include a transmitter photonic integrated circuit (PIC) mounted on the carrier. The transmitter PIC may include a plurality of lasers that generate an optical signal when a voltage or current is applied to one of the plurality of lasers. The device may include a first microelectromechanical structure (MEMS) mounted to the substrate. The first MEMS may include a first set of lenses. The device may include a planar lightwave circuit (PLC) mounted to the substrate. The PLC may be optically coupled to the plurality of lasers by the first set of lenses of the first MEMS. The device may include a second MEMS, mounted to the substrate, that may include a second set of lenses, which may be configured to optically couple the PLC to an optical fiber.
