Radiations towards the continuum not only brings non-Hermicity to photonic systems but
also provides observable channels for understanding their intrinsic physics underneath. In …

We develop a semianalytical model to describe bound states in the continuum (BICs) in
photonic crystal slabs. We model leaky modes supported by photonic crystal slabs as a …

The existence of bound states in the continuum (BIC) manifests a general wave
phenomenon first predicted in quantum mechanics by John von Neumann and Eugene …

We consider bound states in the continuum (BICs) in low-contrast dielectric gratings. It is
demonstrated that the BICs originate from the reduced guided modes on the effective …

We consider propagating bound states in the continuum in dielectric gratings. The gratings
consist of a slab with ridges periodically arranged either on top or on both sides of the slab …

The formation of tunable bound states in the continuum (BICs) within photonic crystal (PC)
slabs has been investigated by using a semianalytical coupled-wave theory framework. An …

ABSTRACT A photonic-crystal slab can support bound states in the continuum (BICs) that
have infinite lifetimes but are embedded into the continuous spectrum of optical modes in …

We report bound states in the radiation continuum (BICs) in a single infinitely long dielectric
rod with periodically stepwise modulated permittivity alternating from ε 1 to ε 2. For ε 2= 1 in …

We trace the Q factor of the resonant modes which are limited to bound states in the
continuum (BICs) for N=∞ in the finite array of N dielectric spheres and disks. For the …

Room temperature surface emission is realized on a large area (1.5 mm× 1.5 mm) photonic
crystal quantum cascade laser (PhC-QCL) driven under pulsed mode, at the wavelength …
