Propagation of Electromagnetic Waves in Optically Anisotropic Materials: Polarization and Intensity Behavior

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The polarization change of an arbitrarily polarized wave in an optically anisotropic medium is discussed, focusing on cases where the refractive index, the extinction coefficient, and the two eigenmodes are degenerated. The polarization converges to that of the eigenmode with the lowest extinction coefficient, except when the extinction coefficients ...

Travelling Wave Solutions for Nonlinear Schrödinger Equation with a Higher-Order Dispersive Term

open access: yesAbstract and Applied Analysis, 2013
A nonlinear Schrödinger equation with a higher-order dispersive term describing the propagation of ultrashort femtosecond pulses in optical fibres is considered and is transformed into a second-order nonlinear ordinary differential equation.
