Physicists trap light in nanoresonators for record time

An international team of Russian, Australian and Korean researchers have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator for a record-breaking time, over 200 periods of one wave oscillation. The trap has also been tested as a basis for a light frequency nanoconverter. The results were published in Science. Researchers anticipate drastically new opportunities for subwavelength optics and nanophotonics, including the development of compact sensors, night vision devices, and optical data transmission technologies.
