Resumo

A simple all-optical cross-gain modulation (XGM) wavelength conversion scheme based on a single semiconductor optical amplifier with higher regeneration capabilities is presented. A proof of concept was performed at data rates from 0.6 to 13.5 Gbps for NRZ streams using the KyaTera/FAPESP buried fiber optical testbed. Good results were obtained for large lambda-detuning (>10 nm), including conversion to the same wavelength. The best experiments achieved an improvement in the quality factor (Q-factor) over 4 units with input signals deteriorated by the standard fiber dispersion, with an extinction ratio penalty of 1.5 dB. In addition, the converter presented a small dependence with the relative optical input signal polarization (around 1 dB). (AU)
