Cubic quintic Ginzburg Landau equation as a model for resonant interaction of EM field with nonlinear media Academic Article uri icon


  • AbstractIn this work, we investigate the possibility of approximating saturable nonlinearity, which is commonly used in complex GinzburgLandau equation (CGLE) for modelling resonant interaction of an electromagnetic field with nonlinear media, with cubic-quintic (CQ) nonlinearity. To validate the suggested approximations, we use variational method to estimate 2D analytical solutions of the CGLE with both saturable and CQ nonlinearity. The paper compares three ways to determine parameters of the CQ approximation and discusses the obtained results in terms of accuracy.
