Abstract: A scalable optical interconnect includes a plurality of transmitters, a multiplexing subsystem able to combine the signals of the plurality of transmitters onto one or more transport fibers according to an orthogonal multiplexing scheme, multiple broadband burst-mode receivers structured and positioned so as to be capable of receiving any signal from any one transmitter of the plurality of transmitters, a distribution subsystem structured so as to be able to distribute independently and contemporaneously the signals of every transmitter to every receiver; and one or more selection subsystems structured and arranged so as to be capable of selecting, in less than 1 microsecond, a single channel from within the orthogonal multiplexing scheme. A method and architecture for distributed contention resolution is also disclosed.

Abstract: An optical device protection system provides dedicated and shared protection for a plurality of optical working devices which may include four-port optical working devices. The system includes an optical switch structure for routing an optical signal around an optical device when the optical device exhibits an error condition. A protection optical device performs a desired operation on the optical signal, wherein the optical switch structure directs the optical signal through the protection optical device. The use of liquid crystal switches allows the optical switch structure to sense an incorrect capacitance value associated with the liquid crystal switch. A control signal is then generated in response to the incorrect capacitance value. Thus, the optical device protection system provides flexibility and a low cost method for protecting complex optical devices.

Abstract: An optical switch and WADM uses a channel selector (10) to provide channel selection and reconfigurable operation. The channel selector (10) includes a segmented filter portion (100) and a highly reflecting mirror (110). The channel selectors (10) can be cascaded to form an N-wavelength channel WDM system. The WADM allows for the selection of a wavelength channel from a multitude of channels by moving the appropriate channel selector (10) into t he path of the light beam.
