A growing group of scientists is adapting Brillouin scattering to a new generation of integrated circuits for 5G and broadband networks, sensors, satellite communication, radar systems, and defense.
While the feedback that causes light to scatter inside optical fibers can reduce the strength of an optical signal, this feedback process can also be used to integrate optical information into a chip. Professor Ben Eggleton, director of the University of Sydney Nano Institute, is investigating how to apply photon-phonon interaction, and with others in the field, he has published a paper outlining the history and potential of what scientists refer to as “Brillouin integrated photonics.”
