Gain improvement in L-band EDFA using unpumped EDF in a double pass system
A new gain improvement technique for L-band EDFA is presented. It uses an unpumped EDF in a double-pass configuration in order to effectively suppress and completely exploit the backward ASE. Compared to a conventional single-pass amplifier, the gain coefficient can be improved from 1.5 dB/mW to 3.1...
