Abstract [en]

Heat generation due to photothermal effects in plasmonic nanostructures have generated many important applications, due to the strong enhancement of light absorption through plasmonic resonance at visible and near-infrared region. In this talk, we review our recent experimental efforts on photothermal effects in a metamaterial nanostructure, which has an ultrasensitive heating response owing to plasmonic resonance. We observed close-to-instantaneous fusion and re-shaping of the nanoparticles with a nanosecond pulse train. The generated heat profile has a subwavelength resolution, and the resonance wavelength can be in principle tailored to arbitrary wavelength region by choosing an appropriate geometry for the resonator structure.
