Broad-band polarization-insensitive wavelength conversion at 10 Gb/s

In this letter, we use four-wave mixing in semiconductor optical amplifiers to obtain wavelength conversion of data stream at 10 Gb/s. The wavelength conversion is made independent of polarization and conversion shift by means of a polarization diversity scheme with the use of two pumps proposed in a previous work of ours. The penalty measured is of about 1.2 dB.
