Abstract :
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 2.5 ps soliton pulses into 20 ps 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.
