Dynamic Gain Clamped Amplifier with Backward Injection of a Fabry Perot Laser

We have been experimentally demonstrated an active control technique of dynamic gain-clamped spectra for the erbium-doped fiber amplifiers (EDFA's) by a backward-injected Fabry-Perot (F-P) laser into this EDFA. In addition, employing a short length erbium-doped fiber (EDF) that not cause any gain sa
