Xerox Develops Reconfigurable Optical ADM on a Chip

Xerox has developed a single-chip that integrates a MEMS photonic switch with planar light circuits, providing the functionality of a Reconfigurable Optical Add/Drop Multiplexer (R-OADM). Xerox said it currently has a working prototype 8-channel reconfigurable OADM operating on a single crystal silicon wafer produced using a common semiconductor process. Xerox intends to license the technology to other companies in the optical switching market. The technology builds on a MEMS fabrication platform developed under a grant provided by the National Institute of Standards and Technology.
