ABSTRACT:
A set of three gratings may be operated in a vernier loop fashion to select a particular wavelength from a wavelength division multiplexed system. As a result, an optical add/drop multiplexer may be provided that can be tuned to select a desired wavelength. In one embodiment, the tuning may be done thermo-optically.
