| 1 | Phase-matched third-harmonic generation via doubly resonant optical surface modes in 1D photonic crystals显示文摘Efficient nonlinear conversion requires that interacting optical waves maintain a consistent phase relationship when traveling in a medium despite its dispersion.Birefringent phase-matching,which is often used to compensate for the dispersion,is not applicable to optically isotropic nonlinear materials.Here,we present a one-dimensional photonic crystal structure that allows the propagation of optical surface waves,both at the fundamental and third-harmonic frequencies,as an efficient medium for phasematched third-harmonic generation.A unique advantage of this structure is that the effective refractive indices for the surface waves are similar to the refractive index of air at both frequencies.This allows phase-matching between the first and third harmonics,and a visible collinear beam of the third harmonic is produced at the prism-coupled output.Moreover,these optical surface waves propagate over long distances even if a lossy nonlinear nanofilm is deposited onto the photonic crystal surface.We provide experimental results for third-harmonic generation at a wavelength of 410 nm for a bare dielectric Ta2O5/SiO2 multilayer structure and for the same structure coated with a 15-nm GaAs film. | Valery N Konopsky Elena V Alieva Sergey Yu Alyatkin Alexey A Melnikov Sergey V Chekalin Vladimir M Agranovich | 2016 | Light(Science & Applications)2016，5，1： | 1 |
| 2 | Electrical Excitation of Long-Range Surface Plasmons in PC/OLED Structure with Two Metal Nanolayers显示文摘A current-driven source of long-range surface plasmons(LRSPs)on a duplex metal nanolayer is reported.Electrical excitation of LRSPs was experimentally observed in a planar structure,where an organic light-emitting film was sandwiched between two metal nanolayers that served as electrodes.To achieve the LRSP propagation in these metal nanolayers at the interface with air,the light-emitting structure was bordered by a one-dimensional photonic crystal(PC)on the other side.The dispersion of the light emitted by such a hybrid PC/organic-light-emitting-diode structure(PC/OLED)comprising two thin metal electrodes was obtained,with a clearly identified LRSP resonance peak. | Valery Konopsky Valery Prokhorov Dmitry Lypenko Artem Dmitriev Elena Alieva Giovanni Dietler Sergey Sekatskii | 2020 | Nano-Micro Letters2020，12，3： | 1 |
