An optical modulator is a device which can be used for manipulating a property of light — often of an optical beam, e. Depending on which property of light is controlled, modulators are called intensity modulators, phase modulators, spatial light modulators, etc. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre). This lets devices send lots of data fast and without mistakes. This process dynamically alters properties of an optical carrier wave—such as amplitude, phase, frequency, or polarization—to embed data. These devices play a crucial role in modern optics and photonics, enabling the manipulation of light for various applications. An optical modulator is a critical component in the realm of photonics and optical communications, playing a pivotal role in manipulating light to encode.
