Numerical Study on a Bound State in the Continuum Assisted Plasmonic Refractive Index Sensor
Photonics, 2022 Plasmonic sensors have attracted intensive attention due to their high sensitivity. However, due to intrinsic metallic loss, plasmonic sensors usually have a large full width at half maximum (FWHM) that limits the wavelength resolution. In this paper, we

Chiral bound states in the continuum [PDF]
Physical Review B, 2014 We present a distinct mechanism for the formation of bound states in the continuum (BICs). In chiral quantum systems there appear zero-energy states in which the wave function has finite amplitude only in one of the subsystems defined by the chiral symmetry.

Floquet bound states in the continuum [PDF]
Scientific Reports, 2013 AbstractQuantum mechanics predicts that certain stationary potentials can sustain bound states with an energy buried in the continuous spectrum of scattered states, the so-called bound states in the continuum (BIC). Originally regarded as mathematical curiosities, BIC have found an increasing interest in recent years, particularly in quantum and ...

Topological Floquet bound states in the continuum
Optics Letters, 2022 A honeycomb array of helical waveguides with zigzag-zigzag edges and a refractive index gradient orthogonal to the edges may support Floquet bound states in the continuum (BICs). The gradient of the refractive index leads to strong asymmetry of the Floquet–Bloch spectrum.

Nanophotonics, 2021 There are many reports in the literature of bound states in the continuum (BICs) in systems with up–down mirror symmetry. Semiconductor-based technology requires bulk semiconductor substrates, which impose symmetry breaking in the vertical direction.

Manipulating Optical Scattering of Quasi-BIC in Dielectric Metasurface with Off-Center Hole
Nanomaterials, 2021 Bound states in the continuum (BICs) correspond to a particular leaky mode with an infinitely large quality-factor (Q-factor) located within the continuum spectrum.
