Paper Abstract

All-optical wavelength conversion is demonstrated by using a spectrum-sliced amplified spontaneous emission (ASE) in the semiconductor optical amplifier (SOA) as the probe light and a delay interference configuration. Characteristics of the ASE output in terms of its spectral dependences under the co-propagating injection by a signal light are analyzed theoretically. Analytical expressions for the ASE output in terms of power and phase changes in the wavelength conversion are deduced. An experimental system based on this scheme is built and its operation principles are introduced. System's performances are investigated and several experimental results on measurements of bit error ratios, extinction ratios under different wavelengths and time waveforms as well as eye diagrams are presented.
