Electromagnetic metasurfaces harness subwavelength patterned elements to exert precise control over the phase, amplitude and polarization of incident waves. By engineering anisotropic or chiral ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240076 , discusses spin-controlled generation of a complete polarization set with randomly-interleaved plasmonic metasurfaces.

Left and right circularly polarized light, where the electromagnetic waves spiral in a clockwise and counterclockwise manner as they travel, plays a crucial role in a wide range of applications, from ...

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard engineers ...

The precise generation and manipulation of three-dimensional (3D) vectorial optical fields is essential for emerging applications in volumetric displays, secure data encoding, optical computing, and ...
