In situtunable circular dichroism of flexible chiral metasurfaces composed of plasmonic nanorod trimers

Abstract

The circularly polarized light source is one of the keys to the chiral photonic circuits and systems. However, it is difficult to integrate conventional light-emitting devices with circular polarization converters...

“…Lin et al have deposited a symmetric achiral trimer of nanobars onto an elastomer sheet. [128] Tensile strain breaks the symmetry and produces a continuously tunable CD behavior (Figure 10a). Interestingly, leftand right-handed structures are feasible depending on the axis of the applied strain.…”
