Abstract

We report the use of the genetic algorithm to optimize the parameters of our previously proposed step-changed long-period gratings for gain-flattening of erbium-doped fiber amplifiers (EDFAs). The gain spectrum of an EDFA is flattened within ±0.35 dB over 30 nm through a suitable selection of the cladding mode and the optimization of the grating parameters. An amplitude-mask structure is proposed to simplify the fabrication process of the optimal grating structure.
