What are Electro-Optic Modulators?

Electro-Optic Modulators (EOMs) are devices that use an electric field to modulate the optical properties of a material, typically changing the phase, frequency, amplitude, or polarization of light. These devices are critical components in modern optical communication systems, enabling fast and efficient data transmission.

How Do Electro-Optic Modulators Work?

EOMs operate on the principle of the electro-optic effect, where the refractive index of a material changes in response to an applied electric field. This change in refractive index can alter the light passing through the material, effectively modulating its properties. Common materials used in EOMs include Lithium Niobate and certain semiconductors.
