Gain clamping in double-pass L-band EDFA using a ring resonator
A gain-clamped long-wavelength-band erbium-doped fiber amplifier (L-band EDFA) based on a ring-laser cavity is demonstrated using two C/L-band wavelength-selective couplers. This new design provides improved gain characteristics and high tuneability. The gain is clamped at 11.5 dB with a gain variat...
