    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.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： A transceiver module having a partitioned housing, e.g., a bifurcated or multi-segment housing, is disclosed that allows coupling and alignment of a TOSA arrangement and ROSA arrangement in separate respective portions in order to minimize or otherwise reduce component damage and rework iterations during manufacturing and repair. Technicians may thus perform at least partial assembly and testing of each optical subassembly arrangement in parallel and in relative isolation without necessarily interrupting and/or waiting on completion of the other. In a general sense, each separate portion of the partitioned housing provides a dedicated workspace of about equal dimension for coupling of subassembly components. Each separate portion may lie flat on a tabletop, for instance, which may further simplify manufacturing processes and provide a wide-range of acceptance angles for performing soldering, welding, insertion and coupling of components, visual inspection, fiber routing, and so on.
