Athermalisation for FBGs

Athermalisation for FBG's



Features Application Packaging

Fiber Bragg gratings are sensitive against changes of temperature and strain. The temperature caused wavelength shift for an FBG at 1550 nm is about +10 pm/K. (Therefore standard FBGs are also used as temperature sensors ).

To prevent the gratings from that behaviour, a special package is used. Our patent pending package consist of an assembly of materials with different expansion coefficients which induces a small strain to the FBG, exactly dosed to reduce the wavelength shift to a minimum.

  • FBG's for 50/100/200 GHz DWDM applications
     
  • Wavelength referenced FBG's
     
  • Add/Drop-multiplexers for 100GHz and 50GHz channel spacing
     
  • Laser wavelength stabilising FBG
For an excellence long term stability, the package is epoxy-free and immune against humidity.
