Ultrafast Heat Transfer at the Nanoscale: Controlling Heat Anisotropy

Thermoplasmonics has benefited from increasing attention in recent years by exploiting the photothermal effects within plasmonic nanoparticles to generate nanoscale heat sources. Recently, it has been demonstrated that exciting gold nanoparticles with ultrashort light pulses could be used to achieve high-speed light management and nanoscale heat-sensitive chemical reaction control. In this work, we study non-uniform thermal energy transient distribution inside cross-shaped nanostructures with femtosecond transient spectroscopy coupled to a thermo-optical numerical model, free of fitting parameters. We show experimentally and numerically that the polarization of the excitation light can control the heat distribution in the nanostructures. We also demonstrate the necessity of considering nonthermal electron ballistic displacement in fast transient heat dynamics models

Hybrid Plasmonic Mode by Resonant Coupling of Localized Plasmons to Propagating Plasmons in a Kretschmann Configuration

Metal nanoparticles have the ability to strongly enhance the local electromagnetic field in their vicinity. Such enhancement is crucial for biomolecular detection and is used by techniques such as surface plasmon resonance detection or surface-enhanced Raman scattering. For these processes, the sensitivity strongly depends on the electromagnetic field intensity confined around such nanoparticles. In this article, we have numerically studied an array of metallic nanocylinders, which can sustain localized surface plasmons (LSP). However, the excitation wavelengths of the LSP are not tunable due to their limited dispersion. We have demonstrated a plasmonic mode, the hybrid lattice plasmon (HLP), which is excited in such a periodic array by adding a uniform thin metallic film below it. This mode is a result of a harmonic coupling of the propagating surface plasmons present in such a metallic film with the Bragg waves of the array. It shows a strong confinement of the electromagnetic field intensity around the nanocylinders, similar to the LSP, but the dispersion of this HLP mode is, however, similar to that of the propagating plasmons and, thus, can be tuned over a wide range of excitation wavelengths. The structure was fabricated using electron beam lithography and characterized by a surface plasmon resonance setup. These experimental results show that the HLP mode can be excited in a classical Kretschmann configuration with a dispersion similar to the prediction of numerical simulations
