Investigation of One-Dimensional Photonic Crystal with Nematic Liquid Crystal
Transmission spectra characteristics of one dimension (1-D) photonic crystal (PC) with nematic liquid crystal (NLC) are investigated theoretically and experimentally. Transmission spectra of 1D PC with NLC under different applied voltage were obtained in experiment . With the voltage range from 0 V to 10 V, it shows that relative transmittance of transmission peak is from 48% to 18%, range of photonic band gaps (PBG) is 290 nm, tunable range is 88 nm, full width at half maximum (FWHM) of the transmission peaks is 7 nm. Theoretical result is closed to experimental result comparatively. These properties can make 1-D PC with NLC be applied to tunable optical filters or optical switches.
