Fibercore’s photosenstive (PS) series of fibers
are co-doped with boron and germanium. The
combination of boron and germanium gives
extremely high photosensitivity, whilst
maintaining a relatively large Mode Field
Diameter (MFD). The high photosensitivity level
ensures that high reflectivity Fiber Bragg Gratings
(FBGs) can be inscribed in a short period of time
with or without hydrogen loading the fiber. PS fiber
may be used ‘straight from the shelf’, without
hydrogenation, delivering a strong and consistent
degree of photosensitivity indefinitely.
Advantages:
Extremely high photosensitivity for rapid inscription
of high reflectivity FBGs;
FBG inscription is possible without the need for
Hydrogen loading;
Dual Band PS1250/1500 fiber suitable for 1310nm
and 1550nm applications;
Typical applications:
FBGs 、Fiber lasers、Temperature sensors
Strain sensors、Biomedical sensors
