Opis:: Nonlinear models occur in many areas of applied physical sciences. This paper presents the first integral method to carry out the integration of Schrödinger-type equations in terms of traveling wave solutions. Through the established first integrals, exact traveling wave solutions are obtained under some parameter conditions.

Opis:: This article presents a theoretical and numerical discussion of the reflection and transmission analysis through a lossy left-handed material slab embedded between two semi-infinite dielectric media. The properties of the lossy left-handed material are given in detail and the required equations for the electromagnetic plane wave propagation are derived to solve the problem. The main important contribution of this article is the characterization of left-handed material that is different from its counterpart known in the literature. After introducing the left-handed material slab, the analytical solution is found for the powers carried by an electromagnetic wave. Then, the reflected, the transmitted, and the loss power are computed in terms of the incidence angle, the frequency, and the slab thickness in the numerical results with the emphasis on the loss factor.

Opis:: This paper describes the TE-TM mode conversion in a magneto-optical layer made by a SiO₂/ZrO₂ layer doped with magnetic CoFe₂O₄ nanoparticles. The mode conversion is caused by the Faraday rotation if the magnetization is aligned along the z-axis, parallel to mode propagation. The properties of this phenomenon are simulated using the full-vectorial beam propagation method (BPM). The simulation results show clearly the influence of two parameters in such devices, the first one is the off-diagonal component of tensor that enhances the rotation and the second one, the imaginary diagonal tensor (parameters K ) which makes it suffering from absorption. This result of simulation is an important step to achieve a monolithic integration of optical isolators.

Opis:: Quality factor of two-dimensional photonic crystals microcavity fabricated by SiO₂/ZrO₂ or SiO₂/TiO₂ in which the refractive index varied in the range of 1.51 to 1.58 has been investigated in the present paper. The structure studied consists of circular rods of radius r embedded in air slab, while a is the constant of triangular lattice. Finite difference time domain method with perfectly matched layers was used to calculate the transmission spectrum by FullWAVE software. The results of simulation clearly demonstrate the existences of resonance wavelength of which the position and the highest Q (Q ≈ 4×10⁵) value are strongly affected by refractive index. We demonstrate that the calculated Q factor for the designed cavity increases by a factor of three relative for a cavity without increasing the refractive index.

Opis:: In this work, we theoretically study the use of magneto-photonic crystal for amplification of the magneto-optical effects, to improve the merit factor. A two dimensional magneto-photonic waveguide device, formed by a triangular lattice of air holes, embedded in SiO₂/ZrO₂ matrix doped with magnetic nanoparticles, is used to study the influence of the volume fraction (VF %) on the mode conversion. We have used the beam propagation method (BPM) to simulate the efficiency coefficient in a planar 2D magneto-photonic waveguide. The influence of VF % on propagation length is studied, and an enhancement in Faraday rotation in 2D magneto photonic crystal is achieved, which proves the ability of the structure to produce magneto-photonic crystal isolator.
