“…The experiment result in [28] suggests an at least 5dB to more than 10dB OSNR degradation in the system after the FWM wavelength conversion device. We gradually increase the degradation of OSNR after the OPC process from 0dB to 5dB by controlling the EDFA input into the 99 : 1 coupler and quantify the systems performances again.…”

“…Although there are a number of schemes that can actualize OPC, in all those techniques, the OSNR of the signal at the output will be degraded. The experimental results in [28] and [29] clearly show that, the OPC comes with several up to dozens decibels (dBs) of OSNR degradation. Figure 1.12 shows a wavelength conversion based on four-wave-mixing in silicon nanowire experimental setup and its results for 28GBaud 16QAM signals [28].…”

The continuous growth in the demand of transmission capacity requires high data rates in today's fiber-optic communication systems. Fiber nonlinearity is considered to be the major obstacle in the development of communication capacity. Optical back propagation is one of the ways to address this problem. This thesis explores the performances of optical back propagation under several practical non-ideal conditions. It compares the results of optical back propagation with other nonlinearity control techniques such as digital back propagation and mid-link optical phase conjugation.Optical back propagation is an all optical process which builds into the optical communication systems to compensate for the phase noise caused by fiber nonlinear effects. Aside from previously established simulation results in the literature of optical back propagation under ideal cases, this thesis demonstrates simulation results of optical back propagation under several non-ideal cases. It demonstrates a 5.7dB of power penalty that occurs with a 5dB of optical signal to noise ratio degradation in the system.For further investigation into the optical back propagation system, advanced modulation formats of the optical signals and higher transmission baud rate effects are studied.The results demonstrated in this thesis can also be used to determine the optimum operating system parameters under non-ideal conditions in optical back propagation systems.ii Sommaire La croissance incessante de la demande pour la capacité de transmission crée un besoin pour des taux de transmission de donnéesélevés dans les systèmes de communication par fibres optiques d'aujourd'hui. La non-linéarité de la fibre est considérée comme un obstacle majeur dans le développement de la capacité de communication. La rétro-propagation optique est une des façons de répondreà ce problème. Cette thèse explore les performances de la rétro-propagation optique dans plusieurs conditions pratiques et imparfaites. Les résultats obtenus avec la rétro-propagation optique sont comparésà ceux obtenus avec d'autres techniques de contrôle de la non-linéarité telles que la rétro-propagation numérique et la conjugaison de phase optiqueà mi-chemin.La rétro-propagation optique est un procédé entièrement optique qui s'introduit dans les systèmes de communication optiques pour compenser le bruit de phase causé par les effets non-linéaires de la fibre. En plus des résultats de simulation institués précédemment dans la documentation pour la rétro-propagation dans des conditions idéales, les résultats de simulation pour la rétro-propagation dans des conditions imparfaites sont présentés dans cette thèse. Il est démontré qu'une perte de puissance de 5.7dB est obtenue lorsque la dégradation du rapport signal sur bruit optique dans le système est de 5dB.Pour de plus amples investigations du système de rétro-propagation optique, des formats de modulation avancés pour le signal optique ainsi que l'effet de l'augmentation de la vitesse de transmission en bauds sontétudiés.Les résultats présen...

“…Over the last decades, four-wave mixing (FWM), which is an important effect in nonlinear optics, originating from the third-order nonlinear susceptibility of optical media, has been intensively presented and investigated in many promising optical elements such as silicon-based waveguides [1][2][3], nonlinear optical fibers [4][5][6][7][8][9], semiconductor optical amplifiers [10][11][12][13], semiconductor lasers [14][15][16][17] and other nonlinear waveguides [18][19][20]. It is well known that the nonlinear FWM effect gives rise to some serious limitations, such as crosstalk in dense wavelength division multiplexing (DWDM) technology [21], etc, and needs to be effectively suppressed to increase the potential capacity of optical communications.…”

In this paper, a semiconductor laser system consisting of a conventional multimode Fabry–Pérot laser diode with a built-in external cavity is presented and demonstrated. More than two resonance modes, whose peak levels are significantly higher than other residual modes, are simultaneously supported and output by adjusting the bias current and operating temperature of the active region. Based on this device, dual-pumped nondegenerate four-wave mixing—in which two pump waves and a single signal wave are simultaneously fed into the laser, and the injection power and wavelength of the injected pump and signal waves are changed—is observed and discussed thoroughly. The results show that while the wavelengths of pump wave A and signal wave S are kept constant, the other pump wave B jumps from about 1535 nm to 1578 nm, generating conversion signals with changed wavelengths. The achieved conversion bandwidth between the primary signal and the converted signal waves is broadly tunable in the range of several terahertz frequencies. Both the conversion efficiency and optical signal-to-noise ratio of the newly generated conversion signals are adopted to evaluate the performance of the proposed four-wave mixing process, and are strongly dependent on the wavelength and power of the injected waves. Here, the attained maximum conversion efficiency and optical signal-to-noise ratio are close to −22 dB and 15 dB, respectively.
