Unhackable metasurface holograms: Security technology can lock information with light color and distance
A research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a secure ...
A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...
A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240159, discusses on-chip light control of semiconductor optoelectronic devices using integrated metasurfaces. Since the initial ...
Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...
Lumotive, a Washington based company backed by Bill Gates, recently announced an impressive $45M Series B raise (at a ~$200M valuation) to continue its journey in revolutionizing Light Control ...
A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.
Almost a decade ago, Harvard engineers unveiled the world’s first visible-spectrum metasurfaces – ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior ...
