Abstract

BIC is a promising resonant mode with attractive mode properties such as an infinite quality factor and a vortex far field pattern. UCNPs emit visible photons when they are excited by NIR photons. In this research, we design a BIC metasurface that wavelengths of the BICs are targeted to the NIR excitation wavelength and visible emission band of the UCNPs. As a result of the coupling between the photons and BICs, the vortex emission can be observed in the far-field and PL was significantly enhanced.
