Periodic structures with a sub‐wavelength pitch have been known since Hertz conducted his
first experiments on the polarization of electromagnetic waves. While the use of these …

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

The intensive investment in optical microelectromechanical systems (MEMS) in the last
decade has led to many successful components that satisfy the requirements of lightwave …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

We propose a design that increases significantly the absorption of a thin layer of absorbing
material such as amorphous silicon. This is achieved by patterning a one-dimensional …

A coupled-Bloch-mode model for explaining various optical properties of strongly modulated
subwavelength lamellar gratings is proposed. The model evidences the key role played by …

We demonstrate that symmetry breaking opens a new degree of freedom to tailor energy-
momentum dispersion in photonic crystals. Using a general theoretical framework in two …

Photonic crystal slabs are able to support optical bound states in the continuum. The latter
are eigenmodes of the structure that are truly guided (no radiation leakage) despite the fact …

In this work, we comprehensively review Mie resonator-based and nonlocal resonant
metasurfaces working in the reflection configuration for color printing applications, with …

We experimentally demonstrate excitability in a semiconductor two-dimensional photonic
crystal. Excitability is a nonlinear dynamical mechanism underlying pulselike responses to …
