Nonradiating sources of energy have traditionally been studied in quantum mechanics and
astrophysics but have received very little attention in the photonics community. This situation …

The recently emerged field of Mesotronics provides novel opportunities for subwavelength
magnetic and electric field localization and giant enhancement by mesoscale dielectric …

We consider refractive index sensing with optical bounds states in the continuum (BICs) in
dielectric gratings. Applying a perturbative approach we derived the differential sensitivity …

Herein, we demonstrate a cavity-enhanced hyperspectral refractometric imaging using an all-
dielectric photonic crystal slab (PhCS). Our approach takes advantage of the synergy …

Bound states in the continuum (BICs) have attracted considerable research attention due to
their infinite quality factor (Q‐factor) and extremely localized fields, which drastically …

In this work, we investigate the evanescent field sensing mechanism provided by an all-
dielectric metasurface supporting bound states in the continuum (BICs). The metasurface is …

The ability to control light at the nanoscale is at the basis of contemporary photonics and
plasmonics. In particular, properly engineered periodic nanostructures not only allow the …

The sensitivity of a refractive index sensor based on an optical bound state in the continuum
is considered. Applying Zel'dovich perturbation theory we derived an analytic expression for …

High quality factor (Q) optical biosensors find many applications, from environmental
monitoring to food safety and clinical diagnostics. In particular, bound states in the …

We consider light scattering by dielectric gratings supporting optical bound states in the
continuum. Due to the presence of instantaneous Kerr nonlinearity critical field …
