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: The present disclosure is generally directed to an optical transceiver that includes a multi-channel on-board ROSA arrangement that includes an optical demultiplexer, e.g., an arrayed waveguide grating (AWG) and an array of photodiodes disposed on a same substrate. The array of photodiodes may be optically aligned with an output port of the optical demultiplexer and be configured to detect channel wavelengths and output a proportional electrical signal to an amplification circuit, e.g., a transimpedance amplifier. Each of the photodiodes can include an integrated lens configured to increase the alignment tolerance between the demultiplexer and the light sensitive region such that relatively imprecise bonding techniques, e.g., die bonding, may be utilized while still maintaining nominal optical power.

Abstract: A mirror device for use in an optical subassembly is disclosed that includes at least one surface with a visible indicator to allow a technician to differentiate a highly-reflective surface from relatively less reflective (e.g., un-coated) surfaces. The mirror device may be formed using known approaches, such as through the deposition of a metallic material on to a surface of the mirror device followed by one or more optional coating layers. Before, or after, forming the highly-reflective surface, a visual indicator may be introduced on to a surface of the mirror device that is opposite the highly-reflective surface. The visual indicator may comprise, for example, random scratches/scoring etched from a wire brush or tool, paint, epoxy, ink, or any other indicator that allows a technician to visually differentiate the portion of the mirror device having the visual indicator from the highly-reflective portion.

Abstract: A multi-channel optical transmitter or transceiver includes an optical multiplexer with input and output ports on a single side. The optical multiplexer receives optical signals at different channel wavelengths on a plurality of mux input ports on one side and combines the optical signals into a multiplexed optical signal, which is output on an optical output port on the same side. The optical multiplexer may be located at a distal end of a transceiver or transmitter housing. In one embodiment, the optical multiplexer is a reversed planar lightwave circuit (PLC) splitter including splitter output ports that are used as the mux input ports and a splitter input port that is used as the mux output port. The mux input ports may be optically coupled to respective transmitter optical subassembly (TOSA) modules with optical fibers.

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 a multi-channel TOSA with vertically-mounted MPDs to reduce TOSA housing dimensions and improve RF driving signal quality. In more detail, a TOSA housing consistent with the present disclosure includes at least one vertical MPD mounting surface that extends substantially transverse relative to a LD mounting surface, with the result being that a MPD coupled to the vertical MPD mounting surface gets positioned above an associated LD coupled to the LD mounting surface. The vertically-mounted MPD thus makes regions adjacent an LD that would otherwise be utilized to mount an MPD available for patterning of conductive RF traces to provide an RF driving signal to the LD. The conductive RF traces may therefore extend below the vertically-mounted MPD to a location that is proximate the LD to allow for relatively short wire bonds therebetween.

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: The present disclosure is generally directed to utilizing capacitors stacks with capacitors mounted in a terminal-to-terminal mounting orientation to reduce overall footprint of capacitor arrays for bypass filtering circuits. In an embodiment, each capacitor stack includes at least a first capacitor, a second capacitor, and a ground plane interconnect. The first capacitor includes first and second terminals disposed opposite each other. The first terminal provides a mating surface to couple to the second capacitor, the second terminal couples to a ground plane. The second capacitor includes first and second terminals disposed opposite each other. The first terminal provides a mounting surface to electrically couple to and support the first capacitor, and the second terminal provides a mating surface to electrically and physically couple to the ground plane. Accordingly, the first capacitor can be inverted and mounted atop the second capacitor to eliminate the necessity of wire bonds, for example.

Abstract: The present disclosure is generally directed to a lens clip that defines at least one mounting surface for coupling to and supporting an array of optical components, e.g., a laser diode and associated components, and an optical lens slot to receive and securely hold an array of optical lenses at a predetermined position relative to the optical components to ensure nominal optical coupling. The optical lens slot includes dimensions that permit insertion of each optical lens into the same and restrict travel along one or more axis. Accordingly, disposing an optical lens within the lens slot ensures correct alignment along at least two axis, e.g., Z and X, with the third axis (e.g., Y) extending parallel along the slot to permit lateral adjustment of each lens.
