Abstract :
A review of schemes useful in a number of high-speed all-optical processing functions that exploit the gain saturation of a semiconductor optical amplifier without suffering from usual pattern-related distortions is reported. Application of pulse-limiting amplification to clock recovery and Cross Gain Compression to single and multicast conversion, 2R regeneration for NRZ, RZ and packets are discussed.
