10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM 2010). 2nd IEEE International Workshop on THz Radiation: Basic Research and Applications (TERA 2010)
A fractal-like (Cantor-like) stratified structure of chiral and achiral isotropic layers is considered. Peculiarities of the wave localization, scalability and sequential splitting in the reflected field of both co-polarized and cross-polarized components are studied. The appearing of the additional peak multiplets in stopbands is revealed, and a correlation of their properties with chirality parameter...
In this report results of modeling and experimental researches of the photonic crystal fibers positioning control method based on the analysis of a measured optical field intensity and calculation of its discrete values autoconvolution are represented. Efficiency and accuracy of a method were checked by test image moving on the set size supervised by the certified measuring instrument of small moving.
The one-dimensional dielectric photonic crystals with complex defect layers, consisting of ultrathin superconducting and dielectric sublayers are theoretically studied. The pronounced difference in the transmittivity spectra of the photonic crystals with right-handed and left-handed positions of the superconducting defect sublayer with respect to the dielectric defect sublayer is demonstrated. The...
Spontaneous emission of a quantum dot placed in a 1D photonic band gap structure is analytically studied. Part of energy which remains nonradiated is obtained. It is shown that decay first follows ~t-1/2 law changing to ~t-3/2 law. Analytical expression for the spectrum is obtained. Analytical theory of the Borrmann effect is developed.
The fabrication of two types of one-dimensional magnetophotonic crystals based on double-layer Bi-substituted iron garnet films with low and high Bi content as magnetic active layers is presented. Considerable Faraday effect enhancement in the fabricated multilayer structures is reported.
We calculated isotropic and anisotropic Bragg interaction geometry in silicon based 2D photonic crystals with square and triangle lattice. Bragg angle vs. acoustic wave frequency dependencies are presented and compared for both structures. Further research aims and expected effects are defined.
Optical properties of both symmetrical and asymmetrical modified Fibonacci structures of chiral and achiral isotropic layers are studied. The localization and polarization transformation of linearly polarized waves are considered. The effect of the phase shift compensation in the reflected field is shown in the case of an asymmetrical modified Fibonacci multilayer.
