The GKER Photonics High Power Polarization Insensitive Circulator (GK-HPCIR Series) is a premier optical component designed to meet the rigorous demands of fiber laser and high-performance instrumentation applications. Operating at a central wavelength of 1064 nm with a tolerance of ±10 nm, this circulator ensures efficient signal routing with minimal loss and exceptional isolation. Engineered to handle high optical power, the circulator features a maximum average optical power capacity of 50 W and can endure peak power of up to 20 kW for nanosecond pulses.

This circulator excels in delivering low insertion loss, with typical values of just 0.5 dB at 23°C, and maintains high isolation levels, up to 25 dB, across all polarization states. The device is also distinguished by its low polarization-dependent loss, ensuring consistent performance irrespective of light polarization. With a minimum crosstalk of 45 dB and a return loss of 45 dB, the circulator guarantees excellent signal integrity and minimal interference. The rugged design supports a wide operating temperature range of +10°C to +50°C and is built to withstand storage temperatures as low as 0°C and as high as +60°C.
