FBG (athermal packaged)

Athermal packaging of FBGs allows decreasing temperature sensitivity of the grating resonance wavelength (FBG temperature stabilization). Temperature induced variation of the FBG wavelength can be reduced an order of magnitude within the required or predetermined temperature range.

 

Applications

  • Fiber/semiconductor laser wavelength stabilization;
  • DWDM systems;
  • Spectral references;
  • Wavelength locking.
