Abstract: In general, a temperature control device for use in laser assemblies and optical subassemblies is disclosed that includes at least two electrically conductive terminals to enable flexible electrical coupling to associated components, e.g., monitor photodiodes and laser diodes, and accommodate a range of laser assembly configurations without the necessity of supplying a negative voltage rail. In more detail, a temperature control device consistent with the present disclosure includes a bottom plate, a top plate, and a plurality of semiconductor elements disposed therebetween. The top plate includes a component mounting surface that provides at least a first and second electrically conductive terminal/pad. The first and second electrically conductive terminals/pads can be electrically isolated, e.g., via a gap, and configured to provide first and second voltage potentials respectively.

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.

Abstract: The present disclosure is directed to a keyed optical component assembly that ensures that the same has a proper orientation when press-fit into or otherwise coupled to a complimentary opening of an optical subassembly housing. In an embodiment, the keyed optical component assembly includes a base portion defined by a first end and a second end disposed opposite the first end along a longitudinal axis. A first arcuate region extends from the first end towards the second end and transitions into a tapered region. A second arcuate region extends from the second end towards the first end and also transitions into the tapered region. Therefore, the tapered region extends between the first arcuate region and the second arcuate region, and generally tapers/narrows from the second arcuate region to the first arcuate region. The resulting shape of the base portion may generally be described as an asymmetric tear-drop shape.

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: Techniques for reducing optical fiber bending loss in an optical transceiver are disclosed. In an embodiment, a small form-factor (SFF) optical transceiver housing includes a demultiplexer device, such as an arrayed waveguide grating (AWG) device, having a longitudinal center line that is offset laterally by a distance Doffset from the longitudinal center line of the SFF optical transceiver housing. The lateral offset distance Doffset may advantageously enable an intermediate optical fiber coupling the demultiplexer with an optical coupling receptacle, such as an LC connector, to be routed within the SFF optical transceiver housing in a manner that avoids introducing bends that are less than a minimum bending radius associated with the intermediate optical fiber cable. Thus some embodiments of the present disclosure enable greater tolerance when routing an intermediate optical fiber within housings that would otherwise introduce bending loss by virtue of their constrained dimensions.

Abstract: An optical component holder having a base portion with a chamfered (or step) portion is disclosed herein that allows a technician to position and partially insert the same within an associated opening using a relatively minor amount of force. The chamfered portion of the base portion operates, in a general sense, as a guide that ensures proper alignment of the optical component holder and allows the same to travel a predetermined distance within the opening before being blocked from further travel by “bottoming” out when the wider portion of the base is at the edge of the associated opening. Thus, the chamfered portion provides an alignment feature to provide tactile feedback that indicates to the technician that the optical component holder is aligned and evenly inserted into an associated opening prior to supplying additional force to press the optical component holder fully into a housing.

Abstract: In an embodiment, an optical component assembly is disclosed and is configured to be at least partially disposed within at least one first opening of an optical subassembly housing. The at least one optical component assembly comprising a base extending from a first end to a second end along a longitudinal axis, and a vertical mount disposed on the base and including a first surface that provides a mounting region to couple to an optical component, the first surface defining a vertical axis that extends substantially upright from the base and a horizontal axis that is angled relative to the longitudinal axis of the base at a first angle, the vertical mount further providing a channel that extends through the vertical mount, wherein the channel provides an optical pathway angled relative to the first surface at the first angle, the first angle being substantially between about 15 and 75 degrees.

Abstract: A multi-channel receiver optical subassembly (ROSA) including at least one sidewall receptacle configured to receive and electrically isolate an adjacent multi-channel transmitter optical subassembly (TOSA) is disclosed. The multi-channel ROSA includes a housing with at least first and second sidewalls, with the first sidewall being opposite the second sidewall and including at least one sidewall opening configured to fixedly attach to photodiode assemblies. The second sidewall includes at least one sidewall receptacle configured to receive at least a portion of an optical component package, such as a transistor outline (TO) can laser package, of an adjacent multi-channel TOSA, and provide electrical isolation between the ROSA housing and the TOSA within an optical transceiver. The sidewall receptacle can include non-conductive material in regions that directly or otherwise come into close proximity with the optical component package of the adjacent TOSA.
