We demonstrate experimentally ultrafast inverted and noninverted wavelength conversion (WC) based on a semiconductor optical amplifier (SOA) and an optical bandpass filter (OBF). In the case of small detuning, the WC is inverted regardless if the OBF is blue- or red-shifted with respect to the central wavelength of the converted signal. However the WC is non-inverted when the filter detuning is relatively large. An analytical formula for the transient cross phase modulation is applied to reveal the polarity variation of WC with respect to the OBF detuning. The theoretical detuning values are in good agreement with our experimental results.
