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 …

Materials with relatively small refractive indices (n< 2), such as glass, quartz, polymers,
some ceramics, etc., are the basic materials in most optical components (lenses, optical …

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

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

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 …

Specialized electromagnetic fields can be used for nanoparticle manipulation along a
specific path, allowing enhanced transport and control over the particle's motion. In this …

The photonic nanojet (PNJ) is a narrow high-energy beam that was originally found on the
back side of all-dielectric spherical structures. It is a unique type of energy concentration …

Dielectric microspheres are shown to be capable of confining light in a three-dimensional
region of subwavelength dimensions when they are illuminated by tightly focused Gaussian …
