摘要: | An active control technique of obtaining simultaneously gain-flattened and gain-clamped spectra for erbium-doped fiber amplifiers (EDFA) has been proposed and experimentally demonstrated by injecting Fabry-Perot (F-P) laser light into the EDFA. In the demonstration, our EDFA module could simultaneously reduce gain variation from 10.8 dB to 1.1 dB for a 10 dB input power change and reduce gain flatness from 11.6 dB to 2.0 dB over the operating wavelength range of 1528 nm to 1560 nm. |
