Compact Optical Waveguides Based on Hybrid Index and Surface-Plasmon-Polariton Guidance Mechanisms
Compact Optical Waveguides Hybrid Index Surface-Plasmon-Polariton Guidance Mechanisms
2010/12/6
Surface-plasmon-polariton (SPP) waveguides made of materials available in nature have, in general, been found to suffer from very high absorption loss when light confinement is beyond diffraction limi...
Structural and Optical Properties of In2S3 Thin Films Prepared by Flash Evaporation
In2S3 Thin Films Flash Evaporation
2010/12/7
In2S3thin films were deposited by flash evaporation of In2S3 powder. The effect of annealing in vacuum and under sulphur atmosphere on the structural and optical properties of these films was investig...
Structural, Optical and Electrochromic Properties of Nanocrystalline TiO2 thin Films Prepared by Spin Coating
Electrochromic Properties Nanocrystalline TiO2 thin Films Spin Coating
2010/12/7
Nanocrystalline TiO2 thin filmswere prepared by spin coating on covered glass substrates with an indium tin oxide (ITO) layer. The structural, electrochromic and optical properties of the films were i...
A Study on the Transversal Optical Mode in Amorphous Gallium Arsenide
Far-infrared spectrum a-GaAs transversal optical mode dipole moment matrix element
2010/12/9
Contributions to the far-infrared spectrum corresponding to both dynamical and structural disorders in a-GaAs are examined when frequency coincides with the transversal optical mode. Under these circu...
First-Order Optical Phonon Processes in Amorphous Clusters
First-Order Optical Phonon Processes Amorphous Clusters
2010/12/15
Optical absorption in the far infrared range for amorphous GaAs, SiC and Ge is investigated. Small clusters in the context of dynamical disorder are considered. Average values of the absorption contri...
Some Remarks on Quasi-Solitons in Optical Fibers
Quasi-Solitons Optical Fibers the solitary waves
2010/12/16
In this paper a unique analysis of solitary waves corresponding to the solutions of the non-linear cubicquintic Schr6dinger equation for optical fibers is performed. These results imply that for an in...
This paper is devoted to the analysis of the Plasma-Optical Effect in GaAs PIN photodiodes operating at the infrared range. An approximated expression for the variation of the refractive index in the ...
