This paper assesses the performance of a wavelength converter based on cross-gain modulation in quantum-dot semiconductor optical amplifiers in an interferometer. Patterning-effect free wavelength conversion is achieved with no extinction ratio degradation at 160 Gbit/s.
This paper presents simulation results of the performance of a 160 Gbit/s 2R regenerator based on Quantum-Dot Semiconductor Optical Amplifiers (QD-SOA). The ultra-fast speed of this device is due to the large Cross-Gain Modulation (XGM) bandwidth of QD-SOAs. A Mach-Zehnder Interferometer (MZI) configuration is used to obtain a non-inverted output signal. Wavelength conversion and 2R (Re-amplifying,...
