Boron Doped Photosensitive Fiber

Intrinsically Photosensitive for Grating Fabrication

  • Rapid formation of high reflectivity FBGs – Without hydrogenation
  • For use ‘straight from the shelf’
  • Strong and consistent photosensitivity
  • Indefinite delivery of strong and consistent photosensitivity
  • Compatible with standard telecommunications and pigtailing fiber
  • Minimal excess loss during splicing

Typical Applications:

  • FBGs
  • Fiber lasers
  • Temperature sensors
  • Strain sensors
  • Biomedical sensors
