Long-period grating (LPG) is the transmission type grating, that light is coupled from the LP01 mode to forward- propagation cladding modes LPlm thus providing the function of wavelength dependent losses in optical fiber systems. We design a wavelength selective grating filter with transmission loss -21.2 dB at wavelength of 1531 nm, which can be used as the amplified spontaneous emission suppressor to improve the gain profile in dual-stage erbium- doped fiber amplifiers.
