ABSTRACT:
A re-configurable optical add/drop apparatus separates an optical input signal into a first signal having a plurality of channels and a second signal having a plurality of channels and includes a channel router with drop ports, a wavelength-selective channel attenuator with a controllable polarization modulator, and an optical coupler. The channel router routes the selected channels of the first signal to the drop ports. The wavelength-selective channel attenuator selectively blocks some of the channels of the second signal to produce a third signal. The optical coupler couples the third signal with a fourth signal having a plurality of add channels to produce an optical output signal.
