Chalcogenide glasses (ChGs) are technologically superior materials, and their properties
underpin the demands of whispering gallery mode–based integrated photonic devices. The …

It is well known that a lens-based far-field optical microscope cannot resolve two objects
beyond Abbe's diffraction limit. Recently, it has been demonstrated that this limit can be …

Lenses are by far the most simple tools for visualization. Although they are intrinsically
limited in resolution, recent efforts have aimed at focusing visible light in micro-scale lenses …

Lens-based optical microscopes cannot resolve the sub-wavelength objects overpass
diffraction limit. Recently, research on super-resolution imaging has been conducted to …

Organic-inorganic hybrid materials are derived from the chemical reaction of silane coupling
reagents and metal alkoxides, involving O-Si-C bonds in the matrix. They offer superior …

A mid-IR amplifier consisting of a tapered chalcogenide fiber coupled to an Er 3+-doped
chalcogenide microsphere has been optimized via a particle swarm optimization (PSO) …

We briefly discuss theoretical studies of the optical properties of self-assembled nanolenses,
spintronics of carbon-based materials, and molecular electronics for fast DNA sequencing …

Preparation and application of glass spheres as resonators are discussed. Surface‐tension
mold (StM) and localized‐laser heating (LLH) techniques have been developed to fabricate …

Encapsulation of light to small spheres ensures the highest quality factor (Q factor) to
enhance the interaction between light and materials. In this Account, we describe the …

A surface-tension mold technique that makes use of the wetting properties between glass
melt and a substrate is used to fabricate micrometer-sized solid immersion lens from a high …
