## Abstract A novel device using a phaseβshifted longβperiod grating cascaded with one normal longβperiod grating is designed to flatten the gain spectrum of EDFAs with all of three gain peaks. The experimental results show that the 3βdB bandwidth of flattened EDFA is 46 nm, and gain peakβtoβpeak i
