Gain control in double-pass L-band EDFA using a ring resonator and two-stage configuration
A gain-clamped double-pass long wavelength band erbium-doped fiber amplifier with high clamped-gain and low noise figure is demonstrated using a ring laser. The optical circulator is used at output end of the amplifier to retro-pass the test signal back into the system for enhanced gain. A length of...
