Four-wave mixing analyses for future ultrafast wavelength conversion at 0.64 Tb / s in a semiconductor optical amplifier

Abstract

This paper describes numerical and analytical analyses relating to the use of nonlinear four-wave mixing in a semiconductor optical amplifier medium for anticipated wavelength conversion at ultrahigh data rates of 320 and 640 Gb∕s. The proposed system guidelines and design show that a maximum wavelength shift of 30 nm can be achieved at 640 Gb∕s, while still maintaining an acceptable bit error rate. In addition, the impact of the pump-probe ratio and semiconductor optical amplifier bias current are investigated and the results are reported. © 2014 Society of Photo-Optical Instrumentation Engineers (SPIE) (DOI: 10.1117/1.OE.53.11.116111)
