Laser Reprograms Ultrathin Optical Device Without Electrodes, Pointing to Low-Power Light Control
Researchers have demonstrated an ultrathin optical device that can be temporarily reprogrammed by laser light without electrodes, a step that could simplify how future photonic systems are controlled. The work, reported through Phys.org and related university and science-release channels, uses dyed liquid crystals to enable light-only switching of optical behavior, with potential relevance for energy-efficient sensing, communications, and climate-tech instrumentation.
