Light focusing through a microbead leads to the formation of a photonic nanojet functional
for enhancing the spatial resolution of traditional optical systems. Despite numerous works …

Photonic nanojets have been brought into attention ten years ago for potential application in
ultramicroscopy, because of its sub-wavelength resolution that can enhance detection and …

The photonic nanojet phenomenon is commonly used both to increase the resolution of
optical microscopes and to trap nanoparticles. However, such photonic nanojets are not …

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

The use of nano/microspheres or beads for optical nanolithography is a consolidated
technique for achieving subwavelength structures using a cost-effective approach; this …

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 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 …

Nanostructured surfaces and devices offer astounding possibilities for biomedical research,
including cellular and molecular biology, diagnostics, and therapeutics. However, the wide …

For a long time, light focusing from microspheres has been intensively researched. The
microsphere has been shown to be capable of generating a high intensity beam with sub …

In this paper, we report a system that uses a microsphere to induce a photonic nanojet to
directly write on a sample surface with sub-diffraction limit resolution, while simultaneously …
