Abstract
The present invention provides reconfigurable wavelength division multiplexed systems which include configurable optical routing systems. Through the use of the configurable optical routing systems, optical channel traffic patterns may be flexibly and dynamically determined based on overall system conditions at any particular time. In one embodiment, a dynamically reconfigurable wavelength selector system for a wavelength division multiplexed optical communication system is provided. An optical transfer system includes an input port for receiving at least one of N optical channels from an optical transmission medium. An optical switch is coupled to a first output port of the optical transfer system and includes an optical filter comprised of at least one Bragg grating configured to reflect at least one optical channel toward the optical transfer system on a first switch path and a transmission medium for transmitting the N optical channels on a second switch path. The reflected optical channel exits the optical transfer system through the second output port. In another aspect, the present invention provides a wavelength division multiplexed communication system with optical cross-c…
