Control over the dispersion of the refractive index is essential to the performance of most
modern optical systems. These range from laboratory microscopes to optical fibres and even …

Metasurface is a recently developed nanophotonics concept to manipulate the properties of
light by replacing conventional bulky optical components with ultrathin (more than 104 times …

Quantitative phase imaging (QPI) of transparent samples plays an essential role in multiple
biomedical applications, and miniaturizing these systems will enable their adoption into …

The flat endface of an optical fiber tip is an emerging light-coupled microscopic platform that
combines fiber optics with planar micro-and nanotechnologies. Since different materials and …

By virtue of the extraordinary capability of manipulating the polarization state, amplitude and
phase of electromagnetic fields, metasurfaces can be employed to display holographic or …

Metalens, a prominent application of two-dimensional metasurfaces, has demonstrated
powerful abilities even beyond traditional optical lenses. By manipulating the phase …

Metasurfaces capable of controlling more than two types of optical properties have drawn a
broad interest recently, as they can bring great flexibility and possibilities to the design of …

Preclinical and clinical diagnostics increasingly rely on techniques to visualize internal
organs at high resolution via endoscopes. Miniaturized endoscopic probes are necessary …

Like amplitude, phase and frequency, polarization is one of the fundamental properties of
light, which can be used to record, process and store information. Optical metasurfaces are …
