ABSTRACT:
A wavelength-selective add-drop multiplexer is disclosed for adding and/or dropping spectral components from a wavelength-division-multiplexed optical signal. (1.times.1) or (2.times.2) optical switches are used, either alone or in conjunction with other optical elements, to separate spectral components identified for drop from other spectral components.
