| Summary: | In this letter, we demonstrate the use of a superstructured fiber Bragg grating to preshape optical pulses to obtain 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-based switches, and show that rectangular switching windows can be achieved thereby providing a 5-10-fold reduction in timing jitter sensitivity. Error free penalty free optical time-division-multiplexing switching was readily achieved over a ±7 ps timing mismatch range for the square pulse driven fiber nonlinear optical loop mirror switch versus a ±1 ps range for the switch driven directly with 2.5 ps laser pulses. |
