Surface-Plasmon-Enhanced Third-Order Harmonic Generation of Organic Materials
نویسندگان
چکیده
We design and fabricate metallic photonic crystals that are integrated with highly-efficient third-order nonlinear polymers. Compared with nanoparticle-doped composite materials, metallic photonic crystals are favorable due to the presence of Bragg-grating-modulated surface plasmon polaritons (SPPs) with strong light localization in large spatial volumes to uniformly enhance the harmonic signals. We experimentally observed extraordinary emission of THG signals from the surface-plasmon-enhanced organic thin film using telecommunication wavelength pulsed laser. This hybrid organic-plasmonic nanostructure opens a new avenue to develop innovative nonlinear optical devices.

Second Harmonic Generation for a Dilute Suspension of Coated Particles
We derive an expression for the effective second-harmonic coefficient of a dilute suspension of coated spherical particles. It is assumed that the coating material, but not the core or the host, has a nonlinear susceptibility for second-harmonic generation (SHG). The resulting compact expression shows the various factors affecting the effective SHG coefficient. The effective SHG per unit volume...
متن کاملSecond Harmonic Generation from Organic Optical Waveguides on Diffraction Gratings
We present experimental results of second harmonic generation using a waveguide of PUSC deposited on a silver diffraction grating. The reflected second harmonic signal is enhanced at the angles of resonant excitation of the guided modes or of the surface plasmon. At these angles, we observe unexpected minima in the second harmonic signal, when the second harmonic frequency is situated within th...

We investigate the influence of localized and propagating surface plasmons on third harmonic generation from rectangular apertures in metal films. We designed optimal aperture array structures by using finite-difference time-domain simulations with nonlinear scattering theory. From this design space, we fabricated and measured the third harmonic in the region of maximal performance. We find the...

In this study, for increasing absorption of the active layer in bulk hetero junction (BHJ) organic solar cells (OSCs) we used surface Plasmon effects of metal nano particles (MNPs). We embedded the MNPs inside the active layer and studied the device structure. For shown the results we investigated the model of our structure with Finite Difference Time Domain (FDTD) numerical method and achieved...
