Introduction to the Electro-optic Effect
What Is the Electro-optic Effect
The electro-optic effect is a property of certain materials where their optical characteristics, such as refractive index, change in response to an applied electric field. This phenomenon is pivotal in the development of various photonic devices and technologies.
Electro-optic Coefficients
Electro-optic coefficients measure the extent to which a material's refractive index changes under an electric field. These coefficients are crucial for designing efficient electro-optic modulators and optimizing their performance in different applications.
Applications of the Electro-optic Effect
Electro-optic Modulators
Electro-optic modulators utilize the electro-optic effect to control the phase, amplitude, or polarization of light signals. They are essential components in telecommunications, allowing for the rapid modulation of laser beams used in fiber-optic communication systems.
