Abstract

The Fabry-Perot interferometer (FPI) is conceptually a very simple structure and, in principle, a lossless device when on resonance. Hence the FPI is a versatile and flexible component and a prime candidate for use as a narrowband spectral filter in wavelength division multiplexing systems with channel spacing of the order of nanometers. The FPI with single mode coupled fibers and liquid-crystal filter have high finesse and easy selectively changed wavelength of peak. To effect demultiplexing one of the transmission peaks is tuned to the wavelength of the required channel.
