We demonstrate single-stage gain-clamped L-band Er^3+^-doped fiber amplifier (EDFA) utilizing self-oscillation modes as the control light. The amplifier structure exploits the characteristics of C/L-band coupler to isolate between lasing modes and L-band signal. The self-lasing cavity modes are obta

By using an optical circulator and C/L-band wavelength division multiplexer to recycle the C-band backward ASE, an L-band gainclamped erbium-doped fiber amplifier is presented. We have experimentally studied the static gain clamping property of this amplifier. As the ASE feedback attenuation is set
A gain-clamped two-stage L-band EDFA is demonstrated by simply incorporating two di erent FBGs on both side of EDF in the second stage. It forms a FBG laser at 1560 nm to clamp the gain in the system. The gain is clamped at about 16:5 dB with gain variation of less than 1:0 dB at dynamic range up to
