Asymmetric optical waveguide in one‐dimensional organic microplate

Year: 2025

Type: article

Abstract: Chiral organic materials have garnered significant interest in nanophononics due to their ability to manipulate polarized light and encode optical information. Herein, chiral one‐dimensional (1D) organic microplates based on benzocyclazine form homochiral crystals that exhibit excellent optical waveguiding properties. These microplates exhibited highly asymmetric light propagation that depends on the handedness of circularly polarized light (CPL). These homochiral microplates demonstrated selective transmission, with R‐microplate favouring left‐handed CPL and S‐microplate favouring right‐handed CPL, showcasing distinct optical loss coefficients for each enantiomer. Multichannel light propagation was observed, where the intensity varied based on the excitation position. These results highlight the potential of 1D chiral microplates for advanced nanophotonic devices, offering chiral‐dependent control over light transmission for future applications in optical information processing.
