10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM 2010). 2nd IEEE International Workshop on THz Radiation: Basic Research and Applications (TERA 2010)
A fiber with a sinusoidal modulation of core diameter was fabricated. Management of the soliton fission by means of this fiber is demonstrated experimentally. Effect of stimulated Raman scattering on the soliton fission is discussed. The experimental observations are confirmed through numerical simulations.
We demonstrate an explicit numerical method for accurate calculation of the scattering matrix, and its poles, and apply this method to describing the multi-channel holes scattering in multiple-quantum-wells (MQW) structures. The results of calculations show that in contrast to the single quantum-well case, at some values of MQW parameters the number of S-matrix poles may exceed that of the absolute...
We propose ultra-compact all-optical XOR and AND logic gates based on multi-mode interference (MMI) without using nonlinear optics. Numerical simulations show that the least ON to OFF logic-level contrast ratio is 13.3 dB for XOR logic gate and 4.3 dB for AND logic gate in the whole C-band.
Numerical calculations of energy characteristics of quantum-well structures based on Si1-xGex-Si have been performed using the four-band k·p method. It is shown that varying the thickness of the active layer and the height and width of potential barriers one can control the frequency ω of optical transitions. The analytical expressions for ħω are established, which are in good agreement with the numerical...
Dispersion of linear and non-linear properties of chalcogenide glasses is studied in semi-empirical approach. The process of ultra-short pulse energy deposition into a glass sample is analysed in a numerical model by variation of the Kerr coefficient, multi-photon absorption coefficient and group velocity dispersion coefficient.
