    Abstract: In accordance with an embodiment, a welding assembly is disclosed that allows for a laser assembly to be coupled into a socket of the same and held at a fixed position, e.g., by a mechanical grabber of a welding system. The mechanical grabber may then travel along one or more axis to bring the TOSA module into mechanical alignment with an opening of an associated optical subassembly housing. The welding assembly may further include an alignment member that provides one or more alignment contact surfaces configured to be brought directly into contact with a surface of the associated subassembly housing. When the one or more alignment contact surfaces are “flush” with the surface of the subassembly housing the emission face of the TOSA module is substantially parallel, and by extension, optically aligned with the opening of the associated subassembly housing.

    Abstract: A coaxial transmitter optical subassembly (TOSA) including a side-by-side laser diode and monitor photodiode package, consistent with embodiments of the present disclosure, may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. In an embodiment, the coaxial TOSA includes a laser sub-mount coupled to a mounting region defined by a body of the coaxial TOSA. The laser sub-mount includes a monitor photodiode disposed adjacent to a side of a laser diode such that a sensor region of the monitor photodiode is disposed within, or in close proximity to, a light cone emitted by a light emitting surface of the laser diode. The monitor photodiode is thus configured to directly receive a portion of emitted channel wavelengths from the laser diode for monitoring purposes.

    Abstract: Techniques are disclosed for filling gaps formed between a press-fit component and an optical subassembly housing to introduce a seal or barrier that can prevent or otherwise mitigate the ingress of contaminants. In an embodiment, a layer of sealant material is applied to one or more surfaces of an optical component prior to press-fitting the component into an optical subassembly housing. Alternatively, or in addition to applying sealant to one or more surfaces of an optical component, a layer of sealant material may be disposed on an interface formed between an outer surface of the optical subassembly housing and the optical component press-fit into the same. Techniques disclosed herein are particularly well suited for small form-factor optical subassemblies that include one or more optical components press-fit into openings of a subassembly housing during manufacturing.

    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.
