ABSTRACT:
An optical add/drop multiplexer may be formed using ring resonators. In some embodiments, ring resonators may be used instead of Bragg gratings in a Mach-Zehnder interferometer configuration. One or more wavelengths may be added or dropped or a band pass of wavelengths may be added or dropped in a wavelength division multiplexed system.
