Diploma thesis abstract. Generation and interaction of vector solitary waves in isotropic gyrotropic media with cubic nonlinearity.
student: A.N. Kiryuhin scientific advisor: V.A. Makarov We numerically investigated the propagation modes of light pulses in isotropic gyrotropic media with anomalous frequency dispersion and spatial dispersion of cubic nonlinearity. It was determined that polarization characteristics have non-homogeneous distribution along the pulse. We studied the influence of light and media parameters on these distributions. We found a separation effect of circularly polarized component of the radiation in media with relation of cubic nonlinearity tensors 2 / 1 < 0 and studied the mechanism of this separation. In media with relation 2 / 1 > 0 we studied the process of vector soliton generation. We numerically performed collision of pulses with bell-shaped envelopes and various distributions of polarization characteristics and found interesting process of elliptically polarized pulse generation. After interaction some of them begin to spread and others become vector solitons.
