Our photosensitive 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.

Photosensitive optical fibers provide significant advantages for high volume FBG production lines by dramatically reducing the production time per FBG..A Bragg Grating is a periodic modulation in the fiber’s index of refraction reflecting light with a wavelength of twice the grating period. The grating forms when the fiber is exposed to a periodic pattern of UV light, typically generated with a phase mask. Fiber lasers and DWDM add/drop filters utilize the ability of Bragg Gratings to reflect <99% of the light in a narrow wavelength band (~1 nm). Other uses of fiber gratings include laser diode frequency stabilization and fiber sensors that detect chemicals, mechanical strain, vibration, acceleration or temperature. Gratings may also be chirped to provide dispersion compensation or gain flattening.
F-SBG-13/15 has been designed to match the MFD characteristics of typical, dual-wavelength, 1310nm and 1550nm telecommunications fiber, making it ideal for the fabrication of add-drop multiplexers or Erbium Doped Fiber Amplifier (EDFA) Gain-Flattening Filters (GFFs).
Use Model Number F-PATCH-CUSTOM to configure a custom fiber-optic patch cord using these fibers. You can specify the fiber type, length, jacketing, and input and output connectors.
F-PS980 has been designed to be used to pigtail 980nm EDFA pump diodes, enabling a wavelength-stabilizing (or ‘pump-locking’) grating to be written directly into the pigtail.
The fiber core is boron co-doped and intrinsically photosensitive, without requiring hydrogen doping. The core size is well compatible with the telecom fibers. With this fibers, a 1 nm-wide, 47 dB deep 15 mm-long transmission grating can be written in these fibers within a few minutes by a pulsed Excimer Laser (10 Hz, 0.5 J/cm2, 248 nm).
