| Abstract: | Bragg gratings in few-mode fibers have been formed,written in photosensitive fibers by the phase-mask method. Bragg gratings in few-mode fibers show 2~3 transmission dips in the transmission spectra at about 1.06 μm. The reflectivities are 50%～70%. The characteristics of Bragg gratings in few-mode fibers are analyzed experimentally and theoretically. The temperature sensitivity of the Bragg gratings in few-mode fibers is obtained experimentally about 9~10 pm/℃ as an average from 25℃ to 95℃. |
| Keywords: | Fiber Bragg Gratings(FBG's) Phase Mask Method Few-mode fiber Temperature Sensitivity |
