polarization maintaining fbg

Polarization Maintaining FBG

Polarization Maintaining FBG is inscribed into a polarization maintaining fiber, the use of polarization maintaining fiber can ensure that the polarization direction of linearly polarized light remains unchanged, improve the coherent signal-to-noise ratio, and achieve high-precision measurement of physical quantities.


Applications of Polarization Maintaining FBG


  • Special fiber grating sensor

  • Special fiber grating filter

  • Polarization beam splitter

  • High power fiber laser


Features of Polarization Maintaining FBG


  • Dual center wavelength, low polarization crosstalk

  • Low loss, high birefringence

  • High reliability and high signal-to-noise ratio
