We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

With ultraviolet light being the workhorse of advanced chipmaking, high-resolution microscopy and next-generation optical communication technologies, improving the on-chip control over such light is ...

Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Researchers use circularly polarized light to control the direction of exciton polaritons in 2D semiconductors, enabling new tools for nanoscale photonics. (Nanowerk Spotlight) Directing light along ...

A beamsplitter is an optical device capable of splitting an incident light beam into two. These tools can split both laser and regular light. A beamsplitter can also combine two incoming beams from ...

Researchers from TU Delft and Radboud University, both in The Netherlands, have discovered that the two-dimensional ferroelectric material CuInP 2 S 6 (‘CIPS’) can be used to control the pathway and ...

"Light carries oscillating electric and magnetic fields; in CIPS, these fields couple not just with electrons, but also with the internal electric field created by the displaced copper ions. What ...
