Abstract
We study the nonlinear optical up-conversion of doubly resonant GaP metasurfaces based on bound state in the continuum (BIC) resonances driven by leaky-waveguide modes. The fabricated metasurface is simultaneously illuminated by two excitation beams, pump and signals beams, exciting transverse-electric and -magnetic waveguide modes. The nonlinear mixing of these modes results in generation of strong sum-frequency emission in the visible spectrum. We observe a non-trivial dependence of the sum-frequency emission with the polarization of the pump beam, explained by the excitation of multipoles at the SFG wavelength. A normalized conversion efficiency of 3.5 × 10-5 [W-1] is measured in the forward direction.
