fbg wavelength locker

FBG Wavelength Locker

The wavelength of pump laser diode is varied at different operating temperatures. Fiber Bragg Gratings (FBG) Wavelength Locker with low reflectivity is used to stabilize the wavelength and intensity of optical amplifier pump laser. It can stabilize the channel wavelength to ITU-T Grid standard wavelength in DWDM systems, network monitoring and fiber sensor applications. 

Features of FBG Wavelength Locker

  • High Wavelength Locking Accuracy

  • Extremely Low-Temperature Dependence

  • Low Polarization Dependence

  • Periodical Locking Covers All Channels

Application of FBG Wavelength Locker

  • Wavelength Monitoring

  • Laser Stabilization for Tunable Laser Module

  • Optical Power Monitoring

  • Network Monitoring

  • EDFA pump lasers

  • DFB lasers stabilization for WDM systems

  • Raman system in-fiber resonators
