An Achromatic Twisted Nematic Liquid Crystal Polarization Switch with a Compensated Film
A broadband polarization switch consisting of an active twisted nematic liquid crystal cell and two passive uniaxial compensation films is proposed. The conjugate gradient method was used for optimizing the device parameters. Simulation results indicate that the polarization switch exhibits a broad bandwidth with 400~700 nm, high contrast ratio and fast response time with 20~30 ms.
