Switchable Circularly Polarized Signals with High Asymmetric Factor Triggered by Dual Photonic Bandgap Structure (Small 49/2022)

Abstract

Smart Photonic Materials In article number 2204199, Bin Wang, Jinpeng Li, Guangdong Ying, and co-workers construct a dual photonic bandgap structure to achieve flexible switching of intensity, wavelength, and direction of circularly polarized luminescence accompanied by ultra-high asymmetry factor values. This work provides insights into the real-time manipulation of circularly polarized signals by chiral photonic materials.
