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 …

Metasurfaces have attracted great attention due to their ability to manipulate the phase,
amplitude, and polarization of light in a compact form. Tunable metasurfaces have been …

Optical metasurfaces can offer high-quality multichannel displays by modulating different
degrees of freedom of light, demonstrating great potential in the next generation of optical …

Metasurfaces have opened the door to next-generation optical devices due to their ability to

Secret sharing is a well-established cryptographic primitive for storing highly sensitive
information like encryption keys for encoded data. It describes the problem of splitting a …

In the late nineteenth century, Heinrich Hertz demonstrated that the electromagnetic
properties of materials are intimately related to their structure at the subwavelength scale by …

Optical metasurfaces with subwavelength thickness hold considerable promise for future
advances in fundamental optics and novel optical applications due to their unprecedented …

Metasurfaces are optically thin metamaterials that promise complete control of the wavefront
of light but are primarily used to control only the phase of light. Here, we present an …

Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

This article reviews recent progress leading to the realization of planar optical components
made of a single layer of phase shifting nanostructures. After introducing the principles of …
