Ricky Anthony, Rini Lahiri, Sambhunath Biswas . Study of Power Conversion Efficiency of a Novel Hybrid L-Band Erbium Doped Fiber Amplifier. International Journal of Computer Applications. 44, 14 ( April 2012), 1-4. DOI=10.5120/6328-8688
High gain and low noise figure are desired features of any erbium doped fiber amplifier (EDFA) based configuration. However, in L band region, low power and quantum conversion efficiencies have restricted EDFA based systems. The paper presents simulation studies of a novel EDFA based high L-band gain configuration which implements two different EDF's in bi-directionally pumped manner. The system shows a non-flattened high gain of 36. 6dB for an optimized net EDF of length 30m, pump power of 120mW at 250C. It also presented a high power and quantum conversion efficiencies of 37. 8% and 57. 0%, variations of which are also studied with input signal and pump powers
