Japanese Scientists Create an “Optical Conveyor Belt” of Quasiparticles Using Interference Between Two Lasers

Researchers from RIKEN and NTT Research have recently created an ‘optical conveyor belt’ in semiconductor-based microcavities using interference between two lasers to move the polaritons formed by light and matter inside the microcavity. This is expected to pave the way for device innovations in quantum metrology and quantum information science. In the study, the researchers fine-tuned the frequency difference between the two lasers to enable the conveyor belt to operate at speeds close to the order of 0.1 percent of the speed of light.
