Efficient second harmonic generation from thin films of V-shaped benzo[b]thiophene based molecules.
We have designed an original approach for efficient Second Harmonic Generation of tailored V-shape benzo[b]thiophene molecular systems enabling versatile and flexible one-step, dry and technologically friendly thin film processing. The designed moieties show chi((2)) values at least as high as the reference LiNbO(3) single crystal, without poling processing and matching the constrains of integr...
متن کاملUltrafast Plasmonic Control of Second Harmonic Generation
Efficient frequency conversion techniques are crucial to the development of plasmonic metasurfaces for information processing and signal modulation. In principle, nanoscale electric-field confinement in nonlinear materials enables higher harmonic conversion efficiencies per unit volume than those attainable in bulk materials. Here we demonstrate efficient second-harmonic generation (SHG) in a s...
متن کاملFemtosecond all-optical devices for ultrafast communication and signal processing
Future bandwidth demand in optical communication and signal processing systems will soon exceed 100 Gb s−1 as is commonly forecasted from a throughput experience curve for communication systems. However, such systems cannot be realized without introducing ultrafast, all-optical devices, since existing optoelectronic and electronic devices and integrated circuits would not be able to function at...
متن کاملCharacterization of Domain Ordering in Polymer and Dendrimer Thin Films Using Photoluminescence and Third Harmonic Generation (THG) Near-field Scanning Optical Microscopy (NSOM)
We have utilized the high spatial resolution of near-field scanning optical microscopy (NSOM) to characterize nanoscopic electronic inhomogeneity in as-cast thin films of a light-harvesting dendrimer consisting of coumarin-343 (core) and coumarin-2 (peripheral) chromophores and in thermally annealed thin films of the semiconductive polymer poly(2-methoxy5-(20-ethylhexyloxy)-1,4-phenylene vinyle...
متن کاملThird-harmonic generation in ultrathin films of MoS2.
We observe optical third-harmonic generation in atomically thin films of MoS2 and deduce effective third-order nonlinear susceptibilities on the order of 10(-19) m(2)/V(2), which is comparable to that of commonly used semiconductors under resonant conditions. By measuring the susceptibility as a function of light wavelength, we find significant enhancements of the susceptibility by excitonic re...
