Passively aligned bi-directional optoelectronic transceiver module assembly

摘要

A passively aligned bi-directional optoelectronic transceiver module assembly utilizes a computer generated hologram as a diffractor to split/combine light beams of two different wavelengths. The entire assembly is constructed of monocrystalline silicon which is photolithographically batch processed to provide a low cost, compact structure with precision tolerances which is inherently passively aligned upon assembly.
