Abstract: In general, the present disclosure is directed to an optical turning mirror for receiving channel wavelengths along a first optical path and reflecting the same towards a fiber or photodetector (PD) without the necessity of disposing a highly reflective layer to increase reflectivity. In more detail, the optical turning mirror includes a substantially transparent body, e.g., capable of passing at least 80% of incident wavelengths, that defines an input region with integrated focus lens(es) for receiving channel wavelengths along a first optical path and a reflective surface disposed opposite the input region to direct/launch received channel wavelengths along a second optical path towards an output interface having an angled light-transmissive surface, with the second optical path extending substantially transverse relative to the first optical path.

Abstract: The present disclosure is generally directed to techniques for thermal management within optical subassembly modules that include thermally coupling heat-generating components, such as laser assemblies, to a temperature control device, such as a thermoelectric cooler, without the necessity of disposing the heat-generating components within a hermetically-sealed housing. Accordingly, this arrangement provides a thermal communication path that extends from the heat-generating components, through the temperature control device, and ultimately to a heatsink component, such as a sidewall of a transceiver housing, without the thermal communication path extending through a hermetically-sealed housing/cavity.

Abstract: A light engine is disclosed that includes an optical bench with a mirror etched therefrom to form a single, unitary structure. The integrated mirror may therefore be pre-aligned with an associated light path to reduce light path alignment errors. In an embodiment, the optical bench includes a first end extending to a second end along a longitudinal axis, a laser diode disposed on a mounting surface adjacent the first end of the optical bench and configured to output laser light along a first light path that extends substantially along the longitudinal axis, and an integrated mirror device disposed along the light path to receive and direct the laser light along a second light path to optically couple the laser light to a photonically-enabled complementary metal-oxide semiconductor (CMOS) die, the second light path being substantially orthogonal relative to the first light path.

Abstract: The present disclosure is generally directed to a housing for use with optical transceivers or transmitters that includes integrated heatsinks with a graphene coating to increase thermal dissipation during operation. In more detail, an embodiment of the present disclosures includes a housing that defines at least first and second sidewalls and a cavity disposed therebetween. The first and/or second sidewalls can include integrated heatsinks to dissipate heat generated by optical components, e.g., laser diodes, laser diode drivers, within the cavity of the housing. The integrated heatsinks can include at least one layer of graphene disposed thereon to increase thermal performance, and in particular, to decrease thermal resistance of the heatsink and promote heat dissipation.

Abstract: This present disclosure is generally directed to an optical isolator array with a magnetic base that allows for mounting and alignment of N number of optical isolators modules within an optical subassembly module. In an embodiment, the magnetic base provides at least one mounting surface for coupling to N number of optical isolators, with N being equal to an optical channel count for the optical subassembly (e.g., 4-channels, 8-channels, and so on). The magnetic base includes an overall width that allows for a desired number of optical isolators to get mounted thereon. Each optical isolator can be uniformly disposed along the same axis on the magnetic base and at a distance D from adjacent optical isolators. An adhesive such as ultraviolet-curing (UV-curing) optical adhesives may be used to secure each optical isolator at a predefined position and increase overall structural integrity.

Abstract: An optical transceiver module is disclosed having a housing that includes at least a first housing portion and a second housing portion, each of the first and second housing portions including a base portion having at least one sidewall extending therefrom that defines a compartment. The first housing portion is configured to couple to the second housing portion to form a cavity therebetween. A transmitter optical subassembly (TOSA) arrangement coupled to the base portion of the first housing portion and is electrically coupled to a first flexible printed circuit (FPC). A receiver optical subassembly (ROSA) arrangement is coupled to the base portion of the second housing portion and is electrically coupled to a second FPC. A first shield coupled to at least one of the first housing portion or the second housing portion to reduce electromagnetic interference between the TOSA arrangement and the ROSA arrangement.

Abstract: The present disclosure is generally directed to an optical transceiver module with a locking arrangement that allows the optical transceiver module to be releasably coupled into an associated receptacle of an optical transceiver cage. The locking arrangement includes a handle member with teeth configured to engage notches of an actuating member to allow rotational movement of the handle to be translated into linear movement by the actuating member. The linear movement of the actuating member may be independent of the housing of the optical transceiver module, and as the handle is transitioned from a locked position to a release position such movement of the actuating member can urge release of the locking members of the optical transceiver cage by way of the tab portions of the actuating member. A user may then supply a force, e.g., a pulling force, to remove the unlocked subassembly module from the receptacle.

Abstract: The present disclosure is generally directed to an optical demultiplexer for use in an optical transceiver module having a truncated profile/shape to increase tolerance and accommodate adjacent optical components. In more detail, the optical demultiplexer comprises a body with at least one truncated corner at the input end. The at least one truncated corner allows the optical demultiplexer to be disposed/mounted, e.g., directly, on a densely populated transceiver substrate, e.g., a printed circuit board (PBC), and provide additional tolerance/space for mounting of circuitry and/or components within the region that would normally be occupied by corner(s) of the optical demultiplexer body. The at least one truncated corner may be introduced in a post-production step, e.g., via cut & polishing, or introduced during formation of the optical demultiplexer using, for instance, photolithography techniques.

Abstract: A temperature controlled multi-channel transmitter optical subassembly (TOSA), consistent with embodiments described herein, may be used in a multi-channel optical transceiver. The temperature controlled multi-channel TOSA generally includes an array of lasers to emit a plurality of different channel wavelengths. The lasers may be thermally tuned to the channel wavelengths by establishing a global temperature for the array of lasers such that the amount of heat communicated to each laser is substantially the same. The global temperature may be established, at least in part, by monitoring the shortest channel wavelength and/or a temperature of the lasers. The temperature of the lasers may then get increased via a shared heating device in thermal communication with the lasers until the shortest monitored wavelength substantially reaches the nominal shortest wavelength or the measured temperature substantially equals the global temperature.

Abstract: The present disclosure is generally directed to an optical transceiver module that includes a mounting section for aligning and coupling to associated TOSA modules. In particular, an embodiment of the present disclosure includes TOSA and ROSA components disposed on a printed circuit board assembly (PCBA). The PCBA includes a plurality of grooves at a optical coupling end to provide a TOSA mounting section. Each of the grooves provides at least one mating surface to receive and couple to an associated TOSA module. Opposite the optical coupling end, the PCBA includes an electric coupling section for coupling to, for example, a transmit (RX) circuit that provides one or more electrical signals to drive TOSA modules coupled to the TOSA mounting section.
