Abstract: | A flat-gain output of 13.5 (15.5) dBm is obtained over 30 nm in the L-band with only a 97 (130)-mW pumping of a 980-nm laser diode. Such highly efficient flat-gain L-band erbium-doped fiber amplifiers are achieved by simply adding a regular fiber Bragg grating. An efficient and simple gain-clamping operation is also demonstrated. |
