Beschreibungen/Notizen

• 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.
