A structured light refers to a light field which is "customized" in both space and time, characterized by its unique distribution of amplitude, phase, and polarization state in both space and time.
Optical waves propagating through air or multi-mode fiber can be patterned or decomposed using orthogonal spatial modes, with far-ranging applications in imaging, communication, and directed energy. Yet the systems that perform ...
The future of optical communications just got brighter. In a development reported in Advanced Photonics, researchers from Nanjing University have introduced iso-propagation vortices (IPVs), a novel concept that offers a solution ...
Over the past decade, metasurfaces deploying two-dimensional artificial nanostructures have emerged as a groundbreaking platform to manipulate light across various degrees of freedom. These metasurfaces exhibit significant ...
Unconventional superconducting states are states of superconductivity rooted in physical processes that do not conform with the conventional theory of superconductivity, namely Bardeen, Cooper and Schrieffer (BCS) theory. ...
In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg ...
National University of Singapore (NUS) researchers have introduced an upconversion plasmonphore platform to enable precise control over the polarization of isotropic upconversion nanoparticles (UCNPs). This is achieved by ...
As object identification and three-dimensional (3D) reconstruction techniques become essential in various reverse engineering, artificial intelligence, medical diagnosis, and industrial production fields, there is an increasing ...
Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase ...
Flexible three-dimensional (3D) displays drive innovation in the next-generation display technology, as they allow for the creation of versatile and adaptable displays that can be easily manipulated and customized to fit ...
