Bound states in the continuum (BICs) have attracted attention in photonics owing to their
interesting properties. For example, BICs can effectively confine light in a counterintuitive …

The introduction of bound states in the continuum (BICs) to photonics has revolutionized the
way cavity design and light–matter interactions are thought about in general. BICs can have …

We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic)
meta-atoms with broken in-plane symmetry can support sharp high-Q resonances arising …

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. Their very …

A bound state in the continuum (BIC) is a localized state of an open structure with access to
radiation channels, yet it remains highly confined with, in theory, an infinite lifetime and …

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 …

We describe S4, a free implementation of the Fourier modal method (FMM), which has also
been commonly referred to as rigorous coupled wave analysis (RCWA), for simulating …

The vortex, a fundamental topological excitation featuring the in-plane winding of a vector
field, is important in various areas such as fluid dynamics, liquid crystals, and …

The quality factor (Q), describing the rate of energy loss from a resonator, is a defining
performance metric for nanophotonic devices. Suppressing cavity radiative losses enables …

In contrast to a conventional symmetric Lorentzian resonance, Fano resonance is
predominantly used to describe asymmetric-shaped resonances, which arise from the …
