The effect of injecting of C-band amplified spontaneous emission (ASE) from C-band erbium-doped fiber amplifier (EDFA) on the performance of L-band EDFA is demonstrated using a circulator and broadband fiber Bragg grating (FBG). Injecting a large amount of ASE (VOA=0 dB) clamps the gain at 15.2 dB from -40 to -10 dBm with a gain variation of less than 0.3 dB. Injecting a small amount of ASE (attenuation of 20 dB and above) improves the small signal gain with a negligible noise figure penalty compared to that of an amplifier without the ASE injection. A maximum gain improvement of 3.5 dB is obtained at an attenuation of 20 dB. These results show that the ASE injection technique can be used either for gain improvement or gain clamping in L-band EDFA.
