Experimental Demonstration of ASE Noise Suppression by Soliton Self-Frequency Shift

Amplified spontaneous emission (ASE) noise self-suppression effect on soliton self-frequency shift (SSFS) has been already reported, but its experimental verification has not been demonstrated. In this letter, we experimentally demonstrate ASE noise suppression effect on SSFS using a metric of power penalty on bit error rate (BER) for on-off keying signals before and after ASE noise suppression. We added an additional 1% of ASE noise to the signal generated from an erbium-doped fiber amplifier. In addition, we examined the degradation of power penalties on BER for different percentages of the noise in the signal in simulation to assess the effective range of ASE noise suppression on SSFS.
