Chinese scientists achieve three-state light in hair-thin silicon device
Microcavity tightly traps light while efficiently exchanging energy, enabling stable multi-state optical operation The researchers from Peking University in Beijing and Harbin Engineering University in northeast China achieved multistability requiring only 240 microwatts for the switching power, less than the power consumption of a typical laser pointer.
