Understanding Optical Modulators

Introduction

Optical modulators are essential components in various optical systems, enabling the manipulation of light signals for diverse applications.

Types of Optical Modulators

There are several types of optical modulators available in the market:

Electro-Optical Modulators

Electro-optical modulators utilize the electro-optic effect to modify the refractive index of a material, thereby altering the phase or amplitude of light passing through it. These modulators are widely used in telecommunications, laser technology, and scientific research.

Acousto-Optical Modulators

Acousto-optical modulators rely on acoustic waves to diffract light, enabling frequency or amplitude modulation. They find applications in laser beam steering, spectroscopy, and optical signal processing.

Applications and Suppliers

Various companies offer a range of optical modulators tailored to specific requirements:
