We have studied an all-optical wavelength converter utilizing cross-polarization modulation in a semiconductor optical amplifier, and presented a feedback scheme for polarization based on the monitoring the light intensity of converted signal and adjusting the voltages of the polarization controller, which realized an error-free conversion of 10Gbit/s NRZ signal for more than 2 hours.
A novel wavelength converter based on cross-polarization modulation is optimized for all-optical network application. Stable error-free application result is achieved for 10 Gbit/s NRZ signal after transmission through 80 km single-mode fibers between network nodes without dispersion compensation.
Dynamic model and experimental scheme are presented for a wavelength converter (WC) based on cross-polarization-modulation (CPM) in a semiconductor optical amplifier (SOA). The frequency chirping and transmission characteristics of this WC are investigated.
