The polarization maintaining isolator of GK-PMI series is a high-performance micro optical device designed specifically for fiber amplifiers, fiber lasers, high-speed communication systems, and instrument applications. Here are some key features of this series of isolators:
Low insertion loss: GK-PMI series isolators have low insertion loss, ensuring minimal attenuation of signals when passing through the isolator.
High isolation: Provides high isolation with a minimum isolation of 23 ° C, ranging from 32 to 55 dB for all polarization states, effectively preventing interference from reverse light on the light source.
High Return Loss: The minimum return loss (input/output) is 55 dB, which helps reduce the optical signal reflected back to the light source, lower noise, and improve system performance.
High extinction ratio: The extinction ratio should be at least 18 dB to ensure the purity of polarized light.
High power processing capability: capable of processing an average optical power of up to 300 mW and a peak power of up to 10 kW, suitable for high-power applications.
Excellent environmental stability and reliability: The working temperature range is -5 ° C to+50 ° C, and the storage temperature range is -40 ° C to+85 ° C, ensuring stable performance under different environmental conditions.
Polarization preservation: The device uses PM 980 panda fiber to maintain the polarization state of light, which is crucial for many high-performance optical systems such as polarization sensitive sensors and fiber lasers.
These characteristics make the GK-PMI series polarization maintaining isolators an ideal choice for applications such as fiber lasers, fiber amplifiers, space laser protection, laboratory research, and optical transceivers. By precisely controlling the propagation direction and polarization state of light, these isolators help improve the overall performance and reliability of the system.
