    摘要： In general the present disclosure is directed to a temperature control device, e.g., a TEC, that includes a top plate with at least first and second contact pads to allow for a soldering process to attach optical components to the first contact pad without causing one or more layers of the second contact pad to reflow and solidify with an uneven mounting surface. Thus, optical components such as a focus lens can be mounted to the second contact pad via, for instance, thermal epoxy. This avoids the necessity of a submount to protect the focus lens from the relatively high heat introduced during a soldering process as well as maintain the flatness of the second contact pad within tolerance so that the mounted focus lens optically aligns by virtue of its physical location/orientation with other associated optical components coupled to the first contact pad, e.g., a laser diode.

    摘要： An optical transceiver assembly includes a thermal dual arrayed waveguide grating (AWG) for both multiplexing and demultiplexing optical signals. The thermal dual AWG may be used as an optical multiplexer/demultiplexer with an array of laser emitters and an array of photodetectors to provide a transmitter optical subassembly (TOSA) and a receiver optical subassembly (ROSA) in the optical transceiver assembly. The thermal dual AWG may be formed as a single chip, and a temperature control device, such as thermoelectric cooler (TEC), may be used in the transceiver to stabilize the temperature of the AWG. In an embodiment, an external reflector may be used at a transmit output of the dual AWG to complete the lasing cavities after the AWG, thereby providing a laser array mux assembly. The optical transceiver device may also be part of a larger system, such as a wavelength division multiplexed (WDM) passive optical network (PON).

    摘要： An optical sub-assembly cartridge for use in a multi-channel receiver optical sub-assembly (ROSA) is disclosed and includes pre-aligned demultiplexing optics. The optical sub-assembly cartridge may include a plurality of sidewalls which define a cartridge body and at least partially enclose a cavity therein. A sidewall of the cartridge body may include a sidewall opening configured to allow light to enter the cavity. A first optical filter disposed opposite the sidewall opening may receive light entering the cavity and be configured to pass unassociated channel wavelengths out of the cavity while reflecting associated channel wavelengths to a mirror disposed in the cavity. The mirror may then reflect the received channel wavelengths to a second optical filter within or external to the cavity. The second optical filter may emit a narrow spectrum of channel wavelengths to a photodiode package to convert the same to a proportional electrical signal.

    摘要： The present disclosure is generally directed to a TO can laser package that includes an off-center focus lens integrated into a lens cap to compensate displacement of an associated laser diode. The TO can laser package includes a TO header with a mounting structure for directly electrically coupling an associated laser diode to electrical leads/pins without the use of an intermediate interconnect. The mounting structure displaces the laser diode such that an emission surface, and more particularly, an origin thereof, is displaced/offset relative to a center of the TO header. The integrated lens cap includes a focus lens with an optical center that is offset from a center of the TO header at a distance that is substantially equal to the displacement of the laser diode. Thus, the displacement of the laser diode is compensated for by the off-center focus lens to minimize or otherwise reduce optical misalignment.

    摘要： The present disclosure is generally directed to a lens clip that includes an optical lens slot to securely hold an optical lens at a predetermined position to mitigate effects of post-annealing shift. The lens clip includes a base that provides at least one substrate mating surface for mounting to a substrate, and at least first and second arms extending from the base. The first and second arms extend substantially parallel relative to each other and define at least a portion of an optical lens slot. The optical lens slot is configured to receive at least a portion of an optical lens and securely hold the optical lens at a predetermined position to ensure optical alignment of the optical lens, e.g., relative to an associated laser diode or other optical component, during fixation of the optical lens to the substrate using, for instance, UV-curing optical adhesives.
