Study on Characteristics of Hybrid Pumped Erbium-doped Fiber Amplifiers
The signal gain characteristics of hybrid pumped erbium doped fiber amplifiers (HEDFA) are studied theoretically. The behaviors near gain threshold and saturation regionare analyzed in detail. It shows that HEDFA has higher gain and lower threshold than the usual EDFA which is pumped by one laser source. The conclusion is supported by our experimental results.
