The Pockels Effect is a linear electro-optic phenomenon where the refractive index of certain non-centrosymmetric crystals changes in response to an applied electric field, allowing modulation of light. This effect is widely used in devices such as electro-optic modulators and switches for controlling light in telecommunications and laser systems.

The refractive index of a material quantifies how much light is bent, or refracted, when entering the material from another medium. It is a dimensionless number that indicates how much slower light travels in the material compared to a vacuum, influencing optical properties like reflection and transmission.

Non-centrosymmetric crystals lack a center of symmetry, which gives rise to unique physical properties such as piezoelectricity, pyroelectricity, and optical nonlinearity. These properties make them crucial for applications in sensors, actuators, and nonlinear optical devices.

Telecommunications is the transmission of information over significant distances by electronic means, enabling communication between individuals, businesses, and governments across the globe. It encompasses a wide range of technologies, including telephones, radio, television, and the internet, playing a crucial role in modern society by facilitating instant communication and data exchange.

Laser systems are devices that amplify light through the process of stimulated emission, producing a coherent beam of monochromatic light. They are widely used in various applications such as cutting, welding, medical treatments, telecommunications, and scientific research due to their precision and high intensity.
