Electro-optic materials are materials that exhibit the ability to change their optical properties in response to an electrical field. These include materials such as crystals, ceramics, polymers, and liquids. The electro-optic effect is widely used in various fields such as telecommunications, sensing, and manufacturing industries.

In the manufacturing industry, electro-optic materials are used to create products such as displays, sensors, and optical modulators. For instance, electro-optic materials are used to manufacture liquid crystal displays (LCDs) that are commonly found in various electronic devices such as televisions, smartphones, and laptops. The material is used to control the orientation of the liquid crystal molecules, which determines the amount of light that passes through each pixel, creating an image.

Another common application of electro-optic materials in manufacturing is in the production of optical modulators. These devices are used to control the intensity, phase, and polarization of light. They are commonly used in telecommunications systems such as fiber optic networks to transmit information over long distances. Electro-optic materials are used to create these devices by controlling the refractive index of the material in response to an electric field.

In summary, electro-optic materials are crucial in several manufacturing industries as they enable the production of a range of products that rely on light modulation, such as sensors, optical modulators and displays.
