Abstract:
A frequency-selective system that may be used as, or as part of, an add/drop multiplexer. An input signal is fed to a Mach-Zehnder interferometer configured to drop, or suppress, by destructive interference, a signal component in a first frequency band from among a plurality of frequency bands. One or more bandpass filters in one arm of the Mach-Zehnder interferometer suppress other frequencies, outside of the first frequency band, so that signals at these other frequencies are not suppressed by destructive interference and are present at the output of the Mach-Zehnder interferometer. A coupler connected after the output of the Mach-Zehnder interferometer adds, into the signal path, a replacement for the dropped signal.

Claim (Index 2):
The frequency selective system of  claim 1 , further comprising:\n a second input for receiving an add signal within the first frequency band of the plurality of frequency bands; and a third coupler having a first input connected to an output of the second coupler and a second input connected to the second input of the frequency selective system.
