WebNov 7, 2024 · Avoided crossing of resonances and merging multiple bound states in the continuum (BICs) are parallel means for tailoring the physical properties of BICs. Herein, we introduce a new concept of super quasi-BIC for photonic crystal (PhC) systems where its quality () factor is boosted in both parametric and momentum spaces. Webversely, a wave state with the frequency inside the continuous spectrum can only be a resonance that leaks and radiates out to infinity. This is the conventional wisdom described in many books. A bound state in the continuum (BIC) is an exception to this conventional wisdom: it lies inside the continuum and coexists with extended waves, but it ...

WebJul 19, 2016 · Bound states in the continuum (BICs) are waves that remain localized even though they coexist with a continuous spectrum of radiating waves that can carry energy away. WebFeb 17, 2024 · Bound states in the continuum have shown potential to demonstrate narrow spectral resonances but often require asymmetric geometry and typically feature strong polarization dependence, … toddler games for 2-5 year olds free online
[1912.00451] From bound states to the continuum - arXiv.org
WebQuantum-mechanical examples have been constructed of local potentials with bound eigenstates embedded in the dense continuum of scattering states. The method employed corrects and extends a procedure invented by von Neumann and Wigner. Cases are cited whereby deformation of the local potential causes the continuum bound state to move … WebThe bound state is defined such that the probability density average will be finite at some particular space region when time passes. While for unbounded states, as time passes, … WebMay 3, 2024 · We study the hybrid bound states in continuum (BIC) in time and spectral domain obtained from Eu 3+ /Pr 3+ doped YPO 4 and BiPO 4 crystals. The spectral and time domain BIC originates from the interference between broadband fluorescence (FL) and narrowband super-florescence (SP-FWM) due to the dressing effect and crystal phase … toddler games apps free for fire
