Abstract
This invention concerns a high frequency optical processor suitable for time-division demultiplexing and channel dropping data signals at bit rates of 80-160 Gb/s and beyond, and for carving high frequency pulse streams with low duty cycle from an unmodulated laser source. In further aspects the invention concerns methods for using the high frequency optical processor. In particular the invention comprises a high frequency optical processor, comprising a Mach-Zehnder amplitude modulator (MZM) embedded in a fiber mirror loop in which the loop input and output are joined by a polarization maintaining coupler.
