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

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
A gain clamping technique for the long wavelength band erbium-doped ΓΏber ampliΓΏer (L-band EDFA) is presented. It uses two circulators and a broad band ΓΏber Bragg grating to route wasted backward C-band ASE from the second stage and launch it back into the input end of the ΓΏrst stage of a two-stage a
