Abstract
The tuning characteristics of a twisted nematic (TN) liquid crystal (LC) Fa bry-Perot interferometer (FPI) wavelength filter, which is a basic componen t of wavelength division multiplexed transmission systems, is analyzed usin g coupled mode theory. First, a simplified modeling of the refractive index change in the LC layer is presented. Next, various characteristics of the eigen polarization modes of the LC medium and the cavity are derived analyt ically. Finally, the qualitative interpretation of the behavior of the FPI' s resonance spectrum are given.
