Light-induced second-harmonic generation in an octupolar dye.

چکیده
Quasi-permanent light-induced second-order susceptibility x s2d of octupolar molecules is demonstrated. The octupolar molecule Ethyl Violet was oriented in a solgel matrix by a purely optical poling technique. The method consists of a seeding process based on a nonclassical holographic process with coherent two-frequency mixing. The growth of the induced x s2d is monitored in real time by frequency doubling of the fundamental beam in the sample. The polarization dependence of the signal is used to demonstrate the octupolar symmetry of the induced x s2d. 1995 Optical Society of America

Octupolar metal nanoparticles as optically driven, coherently controlled nanorotors
We predict theoretically that nanoparticles of octupolar symmetry (nanotriangles and nanotetrahedra), whose orientation cannot be affected by means of linear optics, subjected to a coherent mixture of fundamental and second harmonic fields will rotate and orient controlled by the relative phase between these fields. This is due to the generation of the second-harmonic polarization and its inter...
متن کاملThree-dimensional nonlinear optical chromophores based on through-space delocalization.
Six permutations of 4-fold donor and/or acceptor substitution of paracyclophane at the 4, 7, 12, and 15 positions were synthesized to probe the phenomenon of three-dimensional delocalization on the nonlinear optical properties of organic materials. The interplay between through-bond intramolecular charge transfer (ICT) as well as three-dimensional, or through-space, ICT processes gives rise to ...
متن کاملConsiderably Enhanced Second-Harmonic Generation in Resonant U-Shaped Nano-Structures
In this paper, we perform a detailed study of the spectral response of the gold U-shaped nano-structures for different geometrical parameters and polarizations in order to obtain significant localization factor in the wavelength 1.55 μm. The obtained near-field distribution of electric fields reveals that resonances in these nano-structures correspond to the even and odd plasmonic modes dependi...
متن کاملGalerkin Finite-Element Method for the Analysis of the Second Harmonic Generation in Wagon Wheel Fibers
The nonlinear effects of the second harmonic generation have been investigated for the propagation of light along the axis of fibers of wagon wheel cross sectional shape. Nodal finite element formulation is utilized to obtain discretized Helmholtz equations under appropriate boundary conditions. The hierarchical p-version nodal elements are used for meshing the cross section of wagon wheel fibe...
متن کاملTime-delayed Second-harmonic Generation with Nanosecond Broadband Light Pulses: Studies of Femtosecond Dephasing Process of a Monolayer of Adsorbates
A new technique utilizing a broadband incoherent light source and surface second-harmonic generation is proposed for the measurements of the dephasing process of adsorbates. A broadband Fluorescein 548 dye laser having a correlation time of 112 fs was used to measure the dephasing processes of monolayers of rhodamine 6G and retinal molecules adsorbed on glass surfaces. Our experimental data agr...
