Abstract
The optical deflector includes the electro-optical element to deflect light by utilizing its refractive index variation, and it also includes a reflective adjustable optical deflector element with a reflective element to reflect the deflected light. This arrangement provides down-sized optical devices, such as variable optical attenuators, optical shutters, and optical switches, with high response speed and low insertion loss.
