Optical isolators

Optical isolators are devices that allow light to travel in one direction only, preventing unwanted reflections or backscattering from disrupting sensitive equipment like lasers or optical circuits. They work using components like polarizers and magnetic fields to block light traveling backward while allowing forward transmission. This ensures stable operation and protects lasers from damage caused by reflected light, making optical isolators essential in fiber-optic communication systems and laser applications. Their ability to unidirectionally control light enhances system performance and reliability.
