Patent number: 10761280Abstract: A hermetic optical subassembly includes an optical bench having a mirror directing optical signals to/from an optical waveguide, a carrier supporting a photonic device, and an intermediate optical bench having a mirror directing optical signals between the photonic device and the optical bench. The optical bench and the intermediate optical bench optically aligns the photonic device to the waveguide along a desired optical path. In one embodiment, the photonic device is an edge emitting laser (EML). The mirror of the optical bench may be passively aligned with the mirror of the intermediate optical bench. The assembled components are hermetically sealed. The body of the optical benches are preferably formed by stamping a malleable metal material to form precise geometries and surface features. In a further aspect, the hermetic optical subassembly integrates a multiplexer/demultiplexer, for directing optical signals between a single optical fiber and a plurality of photonic devices.Type: GrantFiled: April 8, 2019Date of Patent: September 1, 2020Assignee: CUDOQUANTA FLORIDA, INCInventors: Robert Ryan Vallance, Jeremy Burke, Rand Dannenberg

Publication number: 20170131532Abstract: A solar collector concentrator having a generally hollow, tubular structure that is precision stamped to form a highly reflective inside surface conforming to a geometry that facilitates concentrating incident light/radiation to the output end. The concentrator may be a separate component separately formed by stamping a malleable stock material. The concentrator may be coupled to the base of a reflector in the collector. The concentrator and the reflector may be integrally formed together by stamping a malleable stock material. The relative positions of the integrally defined concentrator and the reflector are therefore passively aligned with high accuracy achieved from precision stamping. The secondary reflector may be formed by stamping.Type: ApplicationFiled: August 12, 2016Publication date: May 11, 2017Inventor: Rand DANNENBERG

Publication number: 20050260419Abstract: An optical coating on a transparent substrate is provided with a temporary layer of carbon as protection during manufacturing against scratches and corrosive environments. When the optical coating and/or substrate are tempered in an atmosphere reactive to carbon, such as air, the layer of carbon is removed as a carbon-containing gas.
