QD Layer Luminescence Enhancement Via Coupling with Disk Metasurface In Trapped Mode Regime

Abstract

The enhancement of luminescence of quantum dots (QD) layer coating the resonant metasurface formed by silicon disks is studied. It was revealed that exciting of trapped mode resonance in metasurface provides much stronger the luminescence enhancement comparing with case of usual dipole resonances. It opens prospective for development of light amplifier and generator based on all-dielectric metasurface.
