Proposal for optical transistor uses light to control light

(PhysOrg.com) — By using one light pulse to control another, researchers have proposed a design for an optical transistor that fulfills the most challenging criteria set forth in a study last year. An optical transistor has long been sought by physicists because it could be used for optical computing, in which photons rather than electrons are used to perform digital computations.
