Bragg Gratings

Fiber Bragg gratings

The Bragg grating workstation is based on femtosecond laser writing. It enables writing on non-sensitive fibers as well as non-silica fibers.

Advantages of femtosecond writing

•Inscription in various non-sensitized fibers, standard silica (and PM) fibers, active fibers, solid core PCF’s and specialty fibers including fluoride, chalcogenide and sapphire.

  • Inscription through the fiber jacket

  • Higher thermal stability compared to UV gratings (>1000℃)
