Abstract

Long-period fiber gratings (LPGs) have significant applications in both the telecommunications and fiber sensing system.1 In some applications, particularly for EDFA gain flattening, multiple peaks and special spectral profile are required. However, the spectrum of an LPG normally has only one attenuation peak around the 1550 nm wavelength range, and so cannot meet this requirement. One simple solution is to concatenate two or more independent LPGs.2
