Abstract :
A new type of semiconductor optical amplifiers (SOAs) that can have a very low-channel crosstalk is proposed and demonstrated. By arranging the order of the gain materials with different saturation power, the SOA crosstalk is greatly reduced. This new type of SOA can be an ideal gain material for wavelength division multiplexed (WDM) amplification and integration in the access and metro environment.
