Flat optics has emerged as a key player in the area of structured light and its applications,
owing to its subwavelength resolution, ease of integration, and compact footprint. Although …

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 …

Imaging polarimetry is one of the most widely used analytical technologies for object
detection and analysis. To date, most metasurface-based polarimetry techniques are …

INTRODUCTION Polarization describes the path along which light's electric field vector
oscillates. An essential quality of electromagnetic radiation, polarization is often omitted in its …

A key goal of metalens research is to achieve wavefront sha** of light using optical
elements with thicknesses on the order of the wavelength. Such miniaturization is expected …

We present a method allowing for the imposition of two independent and arbitrary phase
profiles on any pair of orthogonal states of polarization—linear, circular, or elliptical—relying …

Polarization, one of the fundamental properties of light, is critical for certain imaging
applications because it captures information from the scene that cannot directly be recorded …

Optical vortices (OVs) carrying orbital angular momentum (OAM) have attracted
considerable interest in the field of optics and photonics owing to their peculiar optical …

On-chip polarization-sensitive photodetectors offer unique opportunities for next-generation
ultra-compact polarimeters. So far, mainstream approaches have relied on the anisotropic …

Metasurfaces have become a rapidly growing field of research in recent years due to their
exceptional abilities in light manipulation and versatility in ultrathin optical applications. They …
