Abstract :
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, Re-shaping) regeneration is demonstrated and several performance issues are discussed.
