FBG

  • FBG serves as a wavelength-selective reflective filter by periodically modulating refractive index in the optical fiber core.
  • Wide ranging FBG, from 450nm to 2200nm, is available.
  • Writable on SMF, PMF and part of DCF.
  • Athermal package is also available.
  • Customizable for individual specifications.
  • We offer prototypes from single fiber
