چکیده
This paper presents a simulation study of Quantum-Dot Semiconductor Optical Amplifiers (QD-SOAs) used for wavelength conversion based on Cross-Gain Modulation (XGM). The key characteristics of these devices are presented along with a rate equations model. This model is used to perform XGM simulations. Performance under different operating regimes is analyzed. Near patterning-effect free wavelength conversion is achieved for 40 Gbit/s NRZ signals without detuned filtering.

We present ultrahigh-speed and full C-band tunable wavelength conversions using cross-gain modulation in a quantum-dot semiconductor optical amplifier (QD-SOA). In this study, we successfully demonstrated error-free 320-Gbit/s operation of an all-optical wavelength converter (AOWC) using the QD-SOA for the first time. We also demonstrated full C-band tunable operation of the AOWC in the wavelen...

All optical wavelength conversion is demonstrated at 10 Gbit/s over a wavelength span of 10 nm without any bit loss by the use of Semiconductor Optical Amplifier (SOA) in a Mach-Zehnder configuration. These wavelength conversion architectures are implemented by using SOA cross-gain modulation (XGM) and cross-phase modulation (XPM) techniques. We have compared the results of both techniques on t...
