    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: 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 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.
