Ultrasensitive optical reflectivity in annular nanohole array on Photonic crystal slab based on bound states in the continuum
We investigate optical bound states in the continuum (BICs) supported by a photonic crystal (PhC) slab penetrated with periodic annular holes theoretically. Ultrahigh-quality factor (Q-factor) resonances associated with BICs are obtained with a Q-factor more than 10(8). The BICs can be seen at nonze...
