Electrically tunable liquid-crystal wave plate in the infrared.
Phase retardance of a liquid-crystal-based, electrically tunable wave plate as a function of voltage and incident light intensity at 10.6 microm is measured using the Stokes-MacCullaugh ellipsometry technique. At intensities of up to 900 W/cm(2), device performance is found to be driven by thermal effects and not optically induced reorientation effects.
