Gain-Clamped Double-Pass L-Band Erbium-Doped Fiber Amplifier Using A Ring Laser and Fiber Bragg Grating
A highly efficient gain-clamped long-wavelength-band erbium-doped fiber amplifier (L-band EDFA) using a ring laser in a double-pass system is demonstrated. A broadband fiber Bragg grating (FBG) operating in the L-band region is used to retro-pass the test signal into the system to enhance the gain....
