Abstract
We propose the all-optical signal discriminator which is the key to all-optical regeneration.1,2 A surface-reflection all-optical gate with a low temperature grown Be-doped strained InGaAs/InAlAs MQW saturable absorber,3,4 which is compact and has a wide wavelength range is promising for this application because it offers high extinction ratios, high-speed response, and threshold characteristics.
