Polarization-insensitive tunable liquid crystal Fabry-Perot filter incorporating polymer liquid crystal waveplates

摘要

Abstract: A polarization-insensitive, tunable nematic liquid crystal Fabry-Perot filter incorporating polymer liquid crystal waveplates within the Fabry-Perot cavity is presented. The performance of the filter is evaluated experimentally, and theoretically verified using computational modeling techniques. Fabrication tolerance parameters are considered through theoretical experiments using the numerical model. A typical experimental filter yielded 12 nm tuning range with 13 VAC of applied voltage, with a finesse of 7 at the design wavelength 1550 nm. !14
