Zusammenfassung:An efficient gain‐flattened C‐band Erbium‐doped fibre amplifier is demonstrated using a double‐pass configuration with an IsoGainTM 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 flatgain characteristic. At input signal power of −10 dBm, a flatgain of 25 dB was obtained from wavelength region from 1528 to 1568 nm. This amplifier has the potential to be used in the high channel count dense wavelength division multiplexing system because of its simplicity and low cost. (© 2006 by Astro, Ltd.
