Paper Abstract

In this paper we introduce the characteristic of the long period grating and methods to fabricate LPGs which are used as gain equalization filter to get broadband amplifiers. Long period fiber gratings used to flatten the gain spectrum of erbium-doped fiber amplifiers (EDFA) were fabricated in experiment. The bandwidth of the EDFA is 35 nm with the gain variation no more than +/- 0.5dB.
