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 …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

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 development of classical and quantum information–processing technology calls for on-
chip integrated sources of structured light. Although integrated vortex microlasers have been …

Sharp electromagnetic resonances play an essential role in physics in general and optics in
particular. The last decades have witnessed the successful developments of high-quality (Q) …

Since its discovery, the asymmetric Fano resonance has been a characteristic feature of
interacting quantum systems. The shape of this resonance is distinctively different from that …

A new class of composite materials has emerged which provides a means to control and
manipulate light. These materials, known as photonic crystals, are periodic arrays of …

Recent research in topological photonics has not only proposed and realized novel
topological phenomena such as one‐way broadband propagation and robust transport of …

Image processing has become a critical technology in a variety of science and engineering
disciplines. Although most image processing is performed digitally, optical analog …

In 1929, only three years after the advent of quantum mechanics, von Neumann and Wigner
showed that Schrödinger's equation can have bound states above the continuum threshold …
