Zabolotin A. Optical and magneto-optical properties of one-dimensional photonic crystals with defects

This thesis is devoted to theoretical investigation of a some linear and nonlinear optical effects in magnetic photonic crystals and dielectric photonic crystals contains complex defect (dielectric and superconductor).Transmission of electromagnetic waves through one-dimensional magnetic photonic crystal of finite size with one and two magnetic defects at normal and oblique incidence of radiation on a photonic structure has been theoretically studied. It was shown that optimization of optical and magneto-optical properties of magnetic photonic crystals with two defect layers allows to obtain high values of transmission coefficients and Faraday rotation of polarization plane of electromagnetic wave. It is found that in magnetic photonic crystals which are characterized by third-order optical nonlinearity of Kerr type it is possible to tune Faraday rotation angle simultaneously with maximal values of transmittivity not only with intensity of incident electromagnetic wave, but also with a change of internal magnetic field. Bistable behavior of nonlinear magnetic photonic crystals can be adjusted not only by the intensity of the incident electromagnetic waves, but also by frequency, polarization and external magnetic field. Theoretical investigations of electromagnetic waves transmission through 1D photonic crystal that includes a combined defect layers composed of dielectric and superconductor. It has been also established that the position of defect modes and the value of transmission coefficient are extremely sensitive to either temperature or the changes of the thickness of superconductor component of defect layer.Also present a theoretical analysis of the influence of misfit strain and misfit dislocation on the optical characteristics of a one-dimensional dielectric photonic crystal, where strained sublayers on both sides of each geometrical interface are taken into account. In particular, we analyze the influence of misfit strain and misfit dislocation strain on the position of defect mode.
