Optical Modulators – acousto-optic, electro-optic
An optical modulator is a device which can be used for manipulating a property of light — often of an optical beam, e.g. a laser beam. Depending on which property of light is controlled, modulators are

Optical modulator
An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre). Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc. The easiest way to obtain modulation of intensity of a light beam is to modulate the current driving the light source, e.g. a laser diode. This sort of modulation is c
