WebThe first singly-degenerate mode 1 is a symmetry-protected bound state in the continuum (BIC). The inferior degenerate band (modes 2 and 3) instead shows avoided crossing resonances at Γ splitting, and is associated to a resonance-trapped BIC. The inset shows the transmitted spectrum at θ = 0°. WebJul 5, 2024 · We have investigated theoretically the reflectivity, quality factor, and eigenfrequency for a single slab with zero refractive index. We demonstrate that optical bound states in the continuum can be achieved by the various zero-refractive-index slabs made of epsilon-near-zero, impedance-machted zero-index, or mu-near-zero materials. WebDec 18, 2014 · Optical bound states in the continuum (BICs) have recently been realized in photonic crystal slabs, where the disappearance of out-of-plane radiation turns leaky resonances into guided modes with infinite lifetimes. We show here that such BICs are vortex centers in the polarization directions of far-field radiation. phonetics michael
