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.

This work demonstrates the simulation of two different types of optical fiber amplifiers (OFA) utilizing OptiSystem–10, namely, 3 m length of erbium doped fiber amplifier (EDFA) and 7 km length of Raman fiber amplifier (RFA). The counter-pumped architecture is adopted for both proposed optical amplifiers. The optimum pump power (OPP) for each amplifier determines in which the longest 3–dB flat gain bandwidth (3–dB BW), reasonable average gain level (Gav), proper average noise figure (NFav) and lower gain variation (Gvar) were achieved. The EDFA shows best performance at conventional band (C–band) within the pump power of 30 mW.While the better performance is observed at long band (L–band) within the pump power of 600 mW for the RFA.
