Abstract
AbstractWe have analyzed the four‐wave mixing (FWM) characteristics in semiconductor optical amplifiers (SOAs) with optimum time‐delays between pump and probe pulses by the finite‐difference beam propagation method. This study is very important to achieve the high FWM conversion efficiency and to clarify the timing jitter. From the simulations, we have clarified that the FWM conversion efficiency increases with optimum time‐delays between pump and probe pulses in SOA for short optical pulses. In the experiment, we have found the similar tendency. Therefore, we have obtained an excellent agreement between the simulation and experimental results of high FWM conversion efficiency in SOAs with optimum time‐delays between pulses. © 2007 Wiley Periodicals, Inc.
