3 Ports 1064nm Polarization Maintaining Optical Circulator

The 3 Ports 1064nm Polarization Maintaining Optical Circulator is a high-performance, non-reciprocal passive optical device designed to route light sequentially from Port 1 → Port 2 and Port 2 → Port 3, while preserving the polarization state of the transmitted beam. Operating at 1064 nm, it provides low insertion loss, high isolation, and excellent polarization extinction ratio (PER), ensuring stable and efficient optical signal transmission in polarization-sensitive laser systems.

Constructed with PM980 PANDA fiber, this circulator is optimized for near-infrared operation around 1064 nm and maintains precise polarization alignment, with the slow axis aligned to the key by default. It features high power handling capability, superior environmental stability, and compact design, making it ideal for integration into precision laser setups.

The device is widely used in fiber laser systems, interferometers, optical amplifiers, and polarization-sensitive measurement instruments, where maintaining polarization is essential for optimal performance.

Application Diagrams

Circulator can be used to send optical signals through a single fiber in two directions.
As the picture shows: A Circulator is located at both ends of the fiber. Each Circulator functions to add a signal in one direction while removing the signal in the other.
