All-optical self-induced polarization switching by two-wave mixing in nematic liquid crystalline films and waveguides - From visible to infrared

Research output: Contribution to journalConference articlepeer-review

Abstract

A theoretical description of the steady state process and experimental confirmation of the effect of using infrared lasers in nematic liquid crystal (NLC) films and waveguides was presented. An incident laser Ex travels through the NLC films and generated a noise source filed Ey by scattering from the director axis n⇌ fluctuation. It was found that Ex and Ey can interfere with each other and form a index grating inside the NLC film. The results show that the stimulated gain is weakly dependent on the wavelength.
