Paper Abstract

A novel structure of an electronically tunable Fabry-Perot interferometer is proposed. It consists of double layers of homogeneously aligned liquid-crystal films with the buffing direction orthogonal to each other. A pure resonant wavelength, for excellent polarization-independent properties, was obtained, as both theoretical and experimental results show. It is demonstrated that the power fluctuations are less than 0.5 dB and the extinction ratios up to 7dB for our devices.
