Dielectrics represent a new frontier for surface-enhanced Raman scattering. They can serve
as either a complement or an alternative to conventional, metal-based SERS, offering key …

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 microelements with circular symmetry have shown interesting optical properties:
photonic nanojets (PNJs) and whispering gallery modes (WGMs). They can confine light …

We study in detail a novel type of optical nanoantennas made of high-permittivity low-loss
dielectric particles. In addition to the electric resonances, the dielectric particles exhibit very …

Dielectric microspheres with appropriate refractive index can image objects with super-
resolution, that is, with a precision well beyond the classical diffraction limit. A microsphere is …

This critical review summarizes the developments in the integration of micro-optical
elements with microfluidic platforms for facilitating detection and automation of bio-analytical …

Along with the rapid development of micro/nanofabrication technology, the past few decades
have seen the flourishing emergence of subwavelength-structured materials and interfaces …

We introduce the novel concept of superdirective nanoantennas based on the excitation of
higher-order magnetic multipole moments in subwavelength dielectric nanoparticles. Our …

We report the design of highly efficient optical antennas employing a judicious synthesis of
metallic and dielectric materials. In the proposed scheme, a pair of metallic coupled …

We review a new, rapidly developing field of all-dielectric nanophotonics which allows to
control both magnetic and electric response of structured matter by engineering the Mie …
