Optical bound states in the continuum
WebJun 29, 2024 · Bound states in the continuum (BICs) have received increasing attention from researchers because of their potential applications in photonic crystal fibers, as well as in lasing, sensing, and surface acoustic wave devices. BICs have been experimentally observed in acoustic resonators, photonic crystal slabs, and optical waveguides. 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.

WebAbstract We demonstrate all robust bound states in the continuum in photonic crystal slabs are vortex centers in the polarization directions of far-field radiation. They are robust because they carry quantized topological charges, which are conserved if the system is invariant under parity-time ( PT) and up-down mirror flip operations.
