Chirped FBG (Fiber Bragg Grating)

Alxenses’s Chirped fiber Bragg grating is an in-fiber broadband reflective optical filter. Using advanced fabrication technique and production facilities, grating period and refractive index modulation depth along the length of FBG can be precisely controlled to produce chirped fiber Bragg grating with different spectral and dispersion characteristic. The broad bandwidth and customizable spectral shape of chirped fiber Bragg grating is particularly effective in gain and spectral flattening of EDFA or ASE optical source.


  • Low insertion loss
  • Customize reflection spectrum
  • Wide bandwidth


  • ASE filtering
  • EDFA gain flattening
  • Broadband reflector for fiber laser
  • Dispersion compensation
