【Abstract】 Based on the fabricated SOA, 140?Mbit/s and 2.5?Gbit/s FWM wavelength conversion are achieved, even if the frequency detuning is higher than 3.75?THz. Experimental study on conversion efficiency versus frequency detuning is also carried out, and the results show that conversion efficiency will decrease rapidly with the frequency detuning increase, and conversion efficiency in wavelength up conversion is lower than that in wavelength down conversion.更多还原
