New photon control cuts the ‘backscatter’

A new device produces a synthetic magnetism to exert virtual force on photons similar to the effect of magnets on electrons.

The advance could yield a new class of nanoscale applications that use light instead of electricity.

“This is a fundamentally new way to manipulate light flow. It presents a richness of photon control not seen before,” says Shanhui Fan, a professor of electrical engineering at Stanford University and senior author of the study.
