“…At the effect of acoustic wave [7,8], temperature [21,22], twisting [23,24], and bending process on LPGs, the fluctuations are decreased in around 30 nm on bandwidth by LPG length more than 51 mm. However, we observed gain flattening around 1 dB due to new design of LPG on extended bandwidth by employing simple equipments.…”

Abstract:A new type of gain flattening filter for amplified spontaneous emission (ASE) source based on erbium doped fiber (EDF) is proposed and demonstrated by fabricating and writing two series ultra-long period fiber grating (ULPFG) on single mode fiber (SMF-28). The novelty method in this research is based on writing the two ULPFGs as fat gratings. The LPG is written by a simple and available arc-discharge method. The pump power based on single-pass backward pump configuration is around 100 mW, and the average wavelength is near to 974 nm. The gain flattening profile is obtained by 3.4 (±1.7) dB ripple in the wavelength range between 1524 nm and 1565 nm with 41-nm band width.
