Question

Quizplus · Accepted Answer

An optical isolator is a passive device designed to allow light to pass through in only one direction, effectively preventing unwanted feedback or reflections in the reverse direction. This is crucial in applications like laser systems where back reflections can damage the source or degrade performance.
