Robust Circularly Polarized Luminescence via Quasi-Bound States in the Continuum in Intrinsic Chiral Silicon Metasurfaces

Xiao-ke Zhu, Yu-Chen Wei, Jose L. Pura +8

We demonstrate a circularly polarized photoluminescence emission, with dissymmetry factors $g_{\mathrm{PL}}$ over 0.1, from achiral organic dye molecules by leveraging quasi-bound st…
