Abstract

Time-resolved spectral analysis is performed on 10 Gb/s signals wavelength converted by four-wave mixing (FWM) in semiconductor optical amplifiers. A pattern-dependent chirp resulting from parasitic gain modulation by the signal is measured and characterized as a function of the converter´s pump-to-probe ratio. This chirp is found to be insignificant for pump-to-probe ratios exceeding 9 dB.
