Abstract

We have demonstrated efficient all-optical polarization conversion of cw 1.55 μm laser in nematic liquid crystal films. The process is mediated by coherent two-beam coupling effect between an incident polarized laser and its orthogonally polarized noise component scattered by the director axis fluctuations. We report here a quantitative theory that accounts for severe pump depletion and high-efficiency polarization conversion and demonstrate good agreement with experimental observations.
