Optics 2025-02-19 v2

Abstract

The absorptive chiral metasurface shows evidence of giant nonlinear chiroptical effects, including chiral third harmonic generation, chiral saturated absorption, and chiral reverse saturable absorption. We finally demonstrate proof of concept circular polarized light limiter based on the refractory chiral Mo metasurface and paves the way for nonlinear chiral sensing, nonlinear hot electron generation, and XOR gate of the all-optical full-adder, showcasing the potential of refractory chiral Mo metasurfaces in overcoming the limitations of traditional chiral plasmonic materials.
