## Abstract This paper reports on dynamically gainβflattened Cβ and Lβband erbiumβdoped fiber amplifiers (DGFβEDFAs), whose dynamic gain ranges are above 20 dB and 24 dB, respectively. This paper gives the detailed test and comparative results for DGFβEDFAs based on the use of a voltageβcontrolled
An efficient gain-flattened C-band Erbium-doped fibre amplifier is demonstrated using a double-pass configuration with an IsoGain^TM^ Erbium-doped fibre (EDF). The amplifier utilizes a double-propagation of signal provided by an optical circulator at the output end of the EDF to obtain an improved f
