In this work, we demonstrate the ability of high-index dielectric particles immersed in air to
generate photonic nanojets with extreme resolution (∼ 0.06 λ0). Both 2D (cylindrical) and …

We present the systematic study of key characteristics (field intensity enhancement, spatial
extents) of the 2D-and 3D-photonic nanojets (PNJs) produced by geometrically-regular …

Photonic nanojets can be created via plane wave irradiation of multi-shaped mesoscale
dielectric particles, and a waist of full-width at half-maximum (FWHM) smaller than the …

Photonic Nanojets are highly localized wave fields emerging directly behind dielectric
microspheres; if suitably illuminated. In this contribution we reveal how different illumination …

We report the direct experimental observation of photonic nanojets created by single latex
microspheres illuminated by a plane wave at a wavelength of 520 nm. Measurements are …

In recent years, it has been demonstrated that micron-scale dielectric spheres and cylinders
can form an intense sharply focused photon beam, termed a photonic nanojet. The photonic …

The three-dimensional real-space observation of photonic nanojet in different microspheres
illuminated by a laser is reported. The finite-difference time-domain technique is used to …

Dielectric microspheres exhibit the ability to focus an incident beam to a subwavelength spot
with strong localized field intensity. In this Letter, a high beam quality of a longitudinally …

This paper reviews the substantial body of literature emerging since 2004 concerning
photonic nanojets. The photonic nanojet is a narrow, high-intensity, non-evanescent light …

We report the phenomenon of ultra-enhanced backscattering of visible light by nanoparticles
facilitated by the 3-D photonic nanojet??? a sub-diffraction light beam appearing at the …
