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 report modelling is produced and characteristics of new types of optical spectral-selective elements of the cylindrical form that use effect of light scattering are considered. Dispersion characteristics of indicatrisse of scattering are calculated.
We analyze the VIPA demultiplexer for different reflection profiles, i.e., uniform, graded, and Gaussian. It is shown that VIPA demultiplexer characteristics can be improved dramatically by innovative reflection profile engineering. These improvements enhance the performance of demultiplexers in UWB-Over-Fiber systems.
Passive polarization converter based on the Bragg reflector with multiple defects is proposed. The structure consists of N distributed Bragg reflectors (DBR) separated by N-1 defects. Transmittance spectra for two orthogonal polarizations of the incident plane wave are presented.
A facilities of composite thick films (from 20 to 100 μkm) based on silver nanoparticles in polymethylmethacrylate matrix (Ag-PMMA) as an optical blooming coatings for any optical devices, in particular, silicon cells are investigated. Decreasing of reflection factor for an optical waves more then on 30% from 400 nm to 1100 nm is shown.
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.
