In this paper we have proposed a novel technique of gain flattening of erbium doped fiber amplifier (EDFA) in which a long period grating is written in the erbium doped fiber (EDF) itself. The salient feature of the proposed technique is that in addition to usual gain flattening, there is an enhance
## 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
