Abstract

An improved scheme for all-optical pulse decision gating by cross-gain modulation(XGM) in semiconductor optical amplifier (SOA) is shown in this paper. Influences of the property of optical clock pulses (including the pulse extinction ratio (ER) and the power) on the shape of regeneration pulse of this optical decision gate are studied by means of numerical simulation and experiment. The power and extinction ratio of optical clock pulses are adjusted in the process of numerical simulation. In the beginning, with the power of clock pulses rising or ER dropping, the pattern of the regeneration pulse gets better and the "1" code noise comes down. There are optimal values of the power and ER of clock pulse for the best pattern of the output pulses. If the ER continues to decrease, the ER of output pulses dropped. Similarly, if the power of clock pulse continues to increase the pattern of the regeneration pulse gets worse. In experiment of optical decision, 40Gb/s regenerated pseudo random bit-sequence (PRBS) data signal was got from degraded PRBS input signal and recovery clock pulses by passing the optical decision gating. The result of experiment is uniform in the numerical simulation.
