    Abstract: An arrayed waveguide grating (AWG) device for use in an optical transceiver is disclosed, and can de-multiplex an optical signal into N number of channel wavelengths. The AWG device can include an AWG chip, with the AWG chip providing a planar lightwave (PLC) circuit configured to de-multiplex channel wavelengths and launch the same into output waveguides. A region of the AWG chip may be tapered such that light traveling via the output waveguides encounters an angled surface of the tapered region and reflects towards an output interface region of the AWG chip. Thus detector devices may optically couple to the output interface region of the AWG chip directly, and can avoid losses introduced by other approaches which couple an output of an AWG to detectors by way of a fiber array or other intermediate device.

    Abstract: A system is provided for aligning a photodetector array to optical outputs of an optical demultiplexer in a multi-channel receiver optical subassembly (ROSA). In one embodiment, the system may include a clamp alignment fixture configured to secure a position of a photodetector mounting bar within a ROSA housing, wherein the photodetector array is disposed on the photodetector mounting bar and the photodetector array includes a plurality of photodiodes. The system may further include a motion staging device configured to adjust an orientation of the photodetector mounting bar by varying an angle of the clamp alignment fixture. The adjustment may be based on observation of the location of an optical alignment signal relative to the plurality of photodiodes, the optical alignment signal projected onto the photodetector mounting bar by the optical demultiplexer.

    Abstract: A coaxial transmitter optical subassembly (TOSA) including a cuboid type TO laser package may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. The cuboid type TO laser package is made of a thermally conductive material and has substantially flat outer surfaces that may be thermally coupled to substantially flat outer surfaces on a transceiver housing and/or on other cuboid type TO laser packages. An optical transceiver may include multiple coaxial TOSAs with the cuboid type TO laser packages stacked in the transceiver housing. The cuboid type TO laser package may thus provide improved thermal characteristics and a reduced size within the optical transceiver.
