Ultrafast Switch from a Bose-Einstein Condensate - Physics

A subpicosecond optical switch demonstrated in a semiconductor material moves researchers a step closer to an all-optical computer.

Quick switch. When “pumped” with an ultraviolet laser pulse, the microwire (light gray strip) acts as a microcavity containing quasiparticles called exciton polaritons that form a Bose-Einstein conde… [+6354 chars]
