Optical Circulator Design

Optical Circulator Design

Explore the fundamentals of Optical Circulators, their design, applications, challenges, and future prospects in optical technology. An Optical Circulator is a non-reciprocal device that routes light from one port to the next, in a unidirectional manner. This unique device has broad applications in. Faraday circulators (or less specifically optical circulators) are a kind of non-reciprocal optical devices. They are technically related to Faraday isolators, and on a broader scale similar to electronic circulators. Introduction Photonic crystals (PCs) are periodic. [pdf]
