Doped and Photosensitive Fibers
Photosensitive Fibers
Thanks to boron and germanium doping, FBGs can be inscribed in photosensitive fibers.
Doped Fibers
Doping with laser-active materials (germanium, erbium, ytterbium, neodymium, etc.) equips optical fibers with special properties.
These are required in certain applications.
