Optical dromions for complex Ginzburg Landau model with nonlinear media

This manuscript studies the optical dromions with beta derivative (BD) applied to the Complex Ginzburg Landau equation (CGLE) with Kerr law, parabolic law, cubic quintic septic law and quadratic cubic law. We obtain bright dromians by using the sine-cosine method (SCM). We will also obtain domain walls with the assistance of Bernoulli equation approach (BEA). Constraint conditions are also listed.
