Optical bound states in the continuum
WebOct 27, 2024 · Stemming from bound states in the continuum (BICs), momentum-space polarization vortices observed in photonic structures provide an attractive approach to generating optical vortex (OV) beams. WebApr 25, 2024 · Bound states in the continuums (BICs) is fundamentally a quantum mechanical process that produces a unique state of light and is considered as a resonant mode of infinite quality factor ( Q) and lifetime [ 1, 2 ]. The possibility of BICs was first time mentioned in 1929 by von Neumann Wigner [ 3 ].

http://ab-initio.mit.edu/~chsu/optical_bic/ 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.
