Light-Driven Plasmonic Color Filters by Overlaying Photoresponsive Liquid Crystals on Gold Annular Aperture Arrays

Light‐driven plasmonic color filters are demonstrated by integrating gold annular aperture arrays with photoresponsive liquid crystals (LCs). Upon photoirradiation, a nematic−isotropic phase transition of the LCs arises from the trans–cis photoisomerization of photochromic LCs. As a consequence, the...

Description
Summary:Light‐driven plasmonic color filters are demonstrated by integrating gold annular aperture arrays with photoresponsive liquid crystals (LCs). Upon photoirradiation, a nematic−isotropic phase transition of the LCs arises from the trans–cis photoisomerization of photochromic LCs. As a consequence, the effective refractive index experienced by the impinging light changes, modulating the transmission intensity.
