Abstract

The authors present a simple configuration for dual-oscillating lasers gain control erbium-doped fiber amplifier (EDFA) in which dual-oscillating lasers are formed by two pairs of fiber Bragg gratings (FBGs). Experimental results show that dual-oscillating lasers dramatically reduce steady and transient gain variations caused by spectral hole burning and relaxation oscillations, and the dual-oscillating lasers gain controlled EDFAs operate satisfactorily with channel's add/drop frequency up to 43 kHz which is significantly larger than that with single-oscillating laser control. Furthermore, we present detail performance of the gain control EDFAs with different dual-oscillating control lasers. Experimental results show that the function of different dual-oscillating lasers is similar. Thus dual-oscillating lasers can be chosen with large spectral space in order not to affect the signals in optical communication window.
