- Abstract
- We introduce an optically controllable color filter model using bi-layered CLC structure. From mathematical parameter sweep analysis using 4×4 matrix method, wavelength controls of red, green, and blue optical color filters and tailored tuning of optical purity in terms of FWHM from 105 nm down to 21 nm at green colored position were confirmed. In addition, an improved color gamut of optical color filters up to 162% of sRGB space in CIE 1931 was first reported. Facile design of custom color filter with controlled wavelength and FWHM, along with enhanced color gamut, can be used for various optical applications.
