Isolators & Circulators

2 µm Polarization Maintaining High Power Fiber Circulator

This 2 µm PM fiber optical circulator is a three-port passive device that transmits high-power light in one direction while directing reverse-propagating light to a third port, maintaining functionality for any state of polarization. Leveraging Our proprietary magneto-optic technology and advanced micro-optic techniques, it offers compact size, high power handling, low loss, and exceptional reliability at a competitive cost. For optical power levels below 20W, heatsink fins are utilized for thermal management, while a proprietary passive liquid cooling system ensures reliable heat dissipation for power levels exceeding 20W. We provides polarization-independent, polarization-maintaining, and custom-designed versions with integrated filter and power monitor, with support for a broad wavelength range and compatibility with specialized fibers.
