Timing jitter tolerant all-optical modulator and demultiplexing systems incorporating pulse-shaping fiber Bragg gratings

摘要

We demonstrate the use of a superstructured fiber Bragg grating to pre-shape optical pulses to obtain more-optimal operation of nonlinear, all-optical switches. Specifically we demonstrate the conversion of 2.5ps soliton pulses into 20ps rectangular pulses at the input to both fiber and semiconductor optical amplifier (SOA-) based switches and show that rectangular switching windows can be achieved thereby providing a 5-10-fold reduction in timing jitter sensitivity.
