Resonant dielectric nanoparticles made of materials with large positive dielectric permittivity,
such as Si, GaP, GaAs, have become a powerful platform for modern light science, enabling …

Dielectric metasurfaces governed by bound states in the continuum (BIC) are actively
investigated for achieving high-quality factors and strong electromagnetic field …

Sensitive and robust detection of gases and chemical reactions constitutes a cornerstone of
scientific research and key industrial applications. In an effort to reach progressively smaller …

Nanoantennas are key optical components that bridge nanometer-scale optical signals to far-
field, free-space radiation. In analogy to radio frequency antennas where tuning and …

Recent advances in nanofabrication have produced increased interest in the scattering and
emission properties of nanoparticles and confined optical sources. In this context, the new …

Wavelength-selective thermal emitters (WS-EMs) hold considerable appeal due to the
scarcity of cost-effective, narrow-band sources in the mid-to-long-wave infrared spectrum …

The goal of antenna design at optical frequencies is to deliver optical electromagnetic
energy to loads in the form of, eg, atoms, molecules or nanostructures, or to enhance the …

In this paper, we review and discuss how nanoantennas may be used to largely enhance
the nonlinear response of optical materials. For single nanoantennas, there have been …

Harnessing the unprecedented spatiotemporal resolution capability of light to detect
electrophysiological signals has been the goal of scientists for nearly 50 years. Yet, progress …
