3-Port Optical Circulator

A 3-port optical circulator is a non-reciprocal device that routes light sequentially from Port 1 → Port 2 → Port 3, ensuring unidirectional signal flow using Faraday rotation and polarization control.

Structure

A typical 3-port optical circulator consists of: Input and output ports: Port 1 (input), Port 2 (intermediate output), and Port 3 (final output) for sequential light routing. Magneto-optic crystal: Usually Terbium Gallium Garnet (TGG), which induces Faraday rotation of the light's polarization under a magnetic field. Polarizing components: Polarizers or birefringent elements that control the polarization state of light, ensuring it follows the designated path.

Fiber connections: Single-mode or polarization-maintaining fibers (e.g., SMF-28e or PM1550) guide light into and out of the circulator with minimal insertion loss. The device is compact and designed to minimize insertion loss (typically
