Abstract

We propose an easy-to-fabricate one-dimensional subwavelength grating as an optimized metamaterial for the excitation of quasi-bound states in the continuum in the near-infrared. Experiment measurements and numerical simulations are in excellent agreement with the presence of near-infrared resonances with a high-quality factor (up to 10⁶) accompanied by a significant increase in electric and magnetic fields (in the order of 10⁴), that can be exploited in many applications in photonics.
