Device boosts interaction between light and motion


(Fundação de Amparo à Pesquisa do Estado de São Paulo) Novel design developed by Brazilian researchers couples light waves and mechanical waves at higher intensity levels. One of its potential applications is in telecommunications as an optical modulator, because the device can sense and excite mechanical vibration, it could be used as an optical switch, turning on or off a laser beam that passes through it far more efficiently than the modulating technologies used today in optical telecommunications networks.
