ABSTRACT:
A passively aligned optical interconnect is described for use as a wavelength division multiplexer (WDM) and demultiplexer. The device makes use of silicon waferboard for a low cost interconnect. Computer generated holograms are used to effect the multiplexing/demultiplexing as well as focusing of the beams. In an alternative embodiment, the device is used as a beam splitter for monochromatic light. In yet another embodiment, the device is used to spatially separate the polarization states of light.
