6. Optical Properties of Nanoparticles in Composite Materials
Abstract : Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields.

7. Structural Information Content of the Optical Field
Abstract : The communication modes are a mathematical technique for the description of structural information in optical fields. These modes are orthogonal, optimally connected functions characteristic of the optical system. Mathematically they are obtained by the singular value decomposition (SVD) of the operator that represents the field propagation. READ MORE

8. DSP based Chromatic Dispersion Equalization and Carrier Phase Estimation in High Speed Coherent Optical Transmission Systems
Abstract : Coherent detection employing multilevel modulation formats has become one of the most promising technologies for next generation high speed transmission systems due to the high power and spectral efficiencies. Using the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.

10. Femtosecond Dynamics of Dissociation and Isomerization Reactions in Solutions
Abstract : The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. READ MORE
