Name: Polarization Maintaining FBG
Brand: AtGrating Technologies.

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
