Nonlinear Optics in Plasmonic Nanostructures
The unique optical properties of plasmon resonances in noble metal nanoparticles have been extensively investigated owing to their ability to enhance the electric field amplitude but also to tailor its spectral and spatial distribution. Among all application domains, nonlinear optics play a singular role since the efficiency of the underlying physical processes are driven by specific symmetry p...
متن کاملNonlinear optics of semiconductor and molecular nanostructures; a common perspective
A unified microscopic theoretical framework for the calculation of optical excitations in molecular and semiconductor materials is presented. The hierarchy of many-body density matrices for a pair-conserving many-electron model and the Frenkel exciton model is rigorously truncated to a given order in the radiation field. Closed equations of motion are derived for five generating functions repre...
متن کاملSynthesis of TiO2-ZnO-ZrO2 Nanocomposites for Nonlinear Optics Applications
A sol-gel technique under ultrasonic irradiation was applied to synthesize ZrO2/TiO2/ZnOnanocomposites. X-ray diffraction analysis confirmed the successful synthesis of nanocomposites. The strain and crystalline size values of ZrO2/TiO2/ZnO nanocomposites are estimated to be 9.98×10-4 and 17.66 nm, respectively. The linear absorption coefficient of ZrO2/TiO2/ZnO nanocomposites was measure...
متن کاملOptics and Nonlinear Buckling Mechanics in Large-Area, Highly Stretchable Arrays of Plasmonic Nanostructures.
Large-scale, dense arrays of plasmonic nanodisks on low-modulus, high-elongation elastomeric substrates represent a class of tunable optical systems, with reversible ability to shift key optical resonances over a range of nearly 600 nm at near-infrared wavelengths. At the most extreme levels of mechanical deformation (strains >100%), nonlinear buckling processes transform initially planar array...
متن کاملoverview of Nonlinear Optics
The invention of the laser provided enough light intensity that nonlinear optics (NLO) could be observed for the first time, almost exactly one year after the first ruby laser – second harmonic generation, observed fifty years ago (Franken, 1961), with a theoretical examination of interactions between light waves in a nonlinear dielectric following very soon thereafter (Armstrong, 1962). The fi...
