Abstract

We propose a novel method for reduction the absorption recovery time in an SOA which acts as saturable absorber. The reduction of the recovery time was successfully demonstrated by stimulated recombination due to a CW additional light(assist light). We also optimize the injection current and the wavelength of the assist light for the reduction effect. The obtained minimum recovery time was less than 50ps. This method can be applied to ultra-high repetition-rate all optical processing.
