Physicists trap light in nanoresonators for record time

An international team of researchers from ITMO University, the Australian National University and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers in size for a record-breaking time. 

In addition, the researchers have provided experimental proof that this resonator may be used as a basis for an efficient light frequency nanoconverter.

Scientists have made suggestions about drastically new opportunities for subwavelength optics and nanophotonics, including the development of compact sensors, night vision devices, and optical data transmission technologies. For instance, the trap has been utilized for a nanodevice capable of changing the frequency, and therefore color, of a light wave.

The paper has been published in Science.
