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)
The surface plasmon-polaritons and waveguide modes in prismatic structures are researched. The metallic layer is deposited on glass prism in the first structure and dielectric layer was deposited on metallic film in the second structure. The reflectance from the metallic layer equal zero at assiduously defined parameters. The first structure has high sensitivity of the minimum reflection angle; the...
Approximate theory of interaction of optical waves with pure reflection gratings at fulfillment of the second and third orders Bragg conditions has been developed. Expressions of the reflectance were obtained. The start-oscillation conditions in gratings with amplification were searched. It is found that reflectance zeros are near generating modes of grating with amplification in gratings without...
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.
The scattering of Gaussian beam on the metamaterial slab with negative refractive index is considered. Modeling is based on the spectral decomposition of the beam field in plane waves. The effect of different parameters on the polarization characteristics of the electromagnetic field reflected from the metamaterial layer and transmitted through it is investigated. The possibility of control of the...
We investigated numerically the reflectivity of aperiodic multilayer mirrors for broadband supercontinuum reflection. It was shown that multilayer mirror based on TiO2/SiO2 with layer thicknesses changed in the nonlinear way can provide high reflectivity from 468 nm to 1600 nm.
