We report a gain improvement of L-band double-pass erbium-doped fiber amplifier (EDFA) by incorporating chirped fiber Bragg grating (CFBG). CFBG has been used to compensate the effect of single mode fiber (SMF) dispersion, reflect the amplified signal back into the gain medium for double pass amplif...
