Abstract
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.
