Abstract
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.
