Abstract: A photodiode package is disclosed that includes a TO-Can style body with an exposed sensor cavity that eliminates the necessity of an encapsulant dispensing process. The TO-Can body of the photodiode package includes an integrated coupling member to allow for coupling to a ROSA housing without an intermediate member. The photodiode package includes a base portion with a cylindrical wall portion that extends therefrom to form an optical coupling cavity. A surface of the base portion provides at least one mounting surface within the optical coupling cavity for coupling to a photodiode chip. The cylindrical wall may function as an integrated coupling member and may be used to directly couple the photodiode package, e.g., without an intermediate cap/ring, into a socket of a ROSA housing. The base portion and cylindrical wall may be formed from a single piece of material, or from multiple pieces depending on a desired configuration.

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 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 coaxial transmitter optical subassembly (TOSA) including a cuboid type TO laser package may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. The cuboid type TO laser package is made of a thermally conductive material and has substantially flat outer surfaces that may be thermally coupled to substantially flat outer surfaces on a transceiver housing and/or on other cuboid type TO laser packages. An optical transceiver may include multiple coaxial TOSAs with the cuboid type TO laser packages stacked in the transceiver housing. The cuboid type TO laser package may thus provide improved thermal characteristics and a reduced size within the optical transceiver.

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.
