Paper Abstract

We have fabricated Long Period Fiber Gratings (LPFG), using non-hydrogenated standard single-mode fiber (SMF28TM), with an electric arc discharge, issued from a commercial splicer. We have obtained gratings with low insertion loss and isolation of 37.5 dB at 1530 nm. The bandwidth at -3 dB (FWHM) is evaluated to be 16 nm. Evolution of the spectral responses (peaks isolation, bandwidth) are explored. We have performed temperature characterization of the realized gratings between 0 degrees C and 750 degrees C. The gratings exhibit a robust and stable behavior to temperature annealing. We showed a spectral shift of the resonance peaks with temperature, these evolutions are worthy of note. We have studied and experimented phase-shift filters. The filters performances are competitive compared to literature. These characterizations provide a set of phenomena to help explanation of the inscription mechanism of the gratings. The fabrication is simple, it does not require to hydrogenate the fiber. The control of the filter parameters makes it possible to produce any filter profile. We have demonstrated the simplicity and flexibility of the process.
