Suppressed angular dispersion of quasi-bound states in the continuum in conical mounting
Bound states in the continuum (BICs) enable high- Q resonances in photonic lattices but are highly sensitive to incident angle, where small deviations broaden resonances and degrade Q -values. We analyze guided-mode resonance (GMR) of one-dimensional (1D) photonic lattices under classical mounting (CM) and fully...
