Abstract
We propose a new configuration for semiconductor optical amplifiers (SOAs), called optical speed-up at transparency (OSAT), which allows to speed up t he gain recovery of SOAs and their saturation power without sacrificing the gain, nor increasing the applied current, The proposed configuration is pa rticularly well-suited for high-speed WDM or OTDM applications, It consists of an optical cw-signal injected at the transparency point of the SOA, Thi s setup is potentially integrable on a single chip, and still relatively fl exible once the device is realized.
