Abstract: The present disclosure is generally directed to a stepped profile for substrates that support “on board” optical subassembly arrangements. The stepped profile enables mounting TOSA modules to the substrate in a recessed orientation to reduce the overall distance between terminals of the substrate and associated components of the TOSA, e.g., RF terminals of the substrate and an LDD of the TOSA. In an embodiment, the stepped profile further simplifies mounting and optical alignment of TOSA modules by providing at least one mechanical stop to engage surfaces of the TOSA modules and limit travel by the same along one or more axis.

Abstract: The present disclosure is generally directed to a monitor photodiode (MPD) submount for use in optical transceivers that includes a body with a conductive trace pattern disposed on multiple surfaces of the same to allow for vertical mounting of an associated MPD and simplified electrical interconnection with TOSA circuitry without the necessity of electrical interconnection. The MPD submount includes a body defined by a plurality of sidewalls. At least one surface of the body provides a mounting surface for coupling to and supporting an MPD. The MPD submount further includes a conductive trace pattern that provides at least one conductive path that is disposed on the mounting surface and on at least one adjoining sidewall. The portion of the at least one conductive path disposed on the adjoining sidewall extends substantially transverse relative to the surface defining the transceiver/transmitter substrate when the MPD submount is coupled to the same.

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: 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: The present disclosure is generally directed to a holder element, also generally referred to herein as a welding element, configured to couple an optical coupling receptacle to a substrate and provide an integrated optical arrangement to redirect light received from the optical coupling receptacle along a receive light path to an output light path that is offset from the receive light path.

Abstract: 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.

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 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.

Abstract: 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.

Abstract: In general, a TOSA consistent with the present disclosure includes a light driving circuit coupled to a hermetically-sealed light engine. The hermetically-sealed light engine includes a housing defined by a plurality of sidewalls. The housing defines a cavity that is hermetically-sealed to prevent introduction of contaminants that would otherwise reduce optical power. The hermetically-sealed light engine optically couples to an external arrayed waveguide grating (AWG), or other multiplexing device, by way of an optical receptacle. The optical receptacle can include a waveguide implemented external to the hermetically-sealed cavity and can include, for instance, an optical isolator, fiber stub, and fiber ferrule section. Thus, the external AWG and associated external optical coupling components advantageously allow for the hermetically-sealed light engine to have a cavity with dimensions relatively smaller than other approaches that dispose an AWG and associated components within a hermetically-sealed cavity.
