Abstract
Disclosed herein are devices, methods, and systems for selectively amplifying optical signals using an optical circuit. The optical circuit includes an input port to receive a plurality of input laser signals and a switching array connected to the input port. The switching array includes a plurality of switching optical amplifiers configured to amplify a laser signal of the plurality of input laser signals as an amplified laser signal and absorb the remaining of the plurality of input laser signals. The optical circuit also includes a splitting circuit connected to the switching array. The splitting circuit is configured to split the amplified laser signal into a plurality of output laser signals.
