Abstract

AbstractThe development of low‐cost and convenient procedure to produce large‐area reconfigurable chiroptical meta‐devices (CMDs) enantiomers with dynamically tunable chiroptical response in the visible band has generated significant interest, owing to its tremendous potential for applications such as optical rotary filtering, color switching, information storage, etc. Currently, many methods, such as phase change material, air pressure, bias, etc., are proposed to reconfigure the chiroptical response of the CMDs enantiomers, but still lack of ability to actively regulate the chiroptical response of the large‐area CMDs. Herein, the centimeter‐scale stressmechanically reconfigurable CMDs enantiomers with actively‐tunable chiroptical response in the visible band is proposed. The chirality sign switching and chirality intensity turning on–off of the CMDs enantiomers can be achieved by bending the flexible substrate to the desired curvature radius to turn the electromagnetic modes resonance of the CMDs enantiomers. The results provide an effective approach to supply the large‐area reconfigurable CMDs enantiomers with actively tunable chiroptical response and will open up new possibilities for chirality nanophotonic applications.
