A new dispersion‐compensated double‐pass erbium‐doped fiber amplifier (EDFA) with high gain and improved noise‐figure characteristics is demonstrated using chirped fiber Bragg grating. The performance is compared with that of the conventional double‐pass EDFA. The signal gain is improved by as much as 18.6 dB at −40‐dBm signal power with negligible noise penalty. The proposed amplifier architecture can improve the signal gain and at the same time compensate the signal dispersion. © 2005 Wiley Periodicals, Inc.
