Abstract
The present invention relates to tunable filters. More specifically, the present invention pertains to a method and apparatus that allows tuning of a wavelength over a large optical band. The disclosed system and method allows an arbitrary wavelength selection of an incoming beam of light. The disclosed system and method may be used in imaging systems like teloscopes or microscopes, or for point sources like laser or optical fibers. Further, in the case of optical fibers, it may be used as an add/drop filter.
