Broad Band Filter FBG



Features Application Packaging

Using the technique of "chirped" (linear variation of the period within the FBG structure) Fiber Bragg gratings, we are able to provide FBGs with a very broad bandwidth and with a high rejection.

We can provide a wide range of center wavelengths, bandwidths, and reflectivities.

  • WDM 1300/1550nm band rejection filter
     
  • ASE filtering, noise suppres- sion
     
  • In-fiber mirrors

Due to their extended physical length, Broad Band FBGs require often a larger packaging than normal FBGs.
