Second-harmonic generation due to coulomb-like interaction in a heterodimer of subwavelength dimensions
Maya H. Shor1, Esti Toledo, Shilpi Shital +4
We experimentally study the optical second harmonic generation (SHG) from deep subwavelength gold-silver heterodimer and silver-silver and gold-gold homodimers. Our results show th…
Ultrafast dynamics of optically-induced heat gratings in metals -- more complicated than expected
Yonatan Sivan, Marat Spector
Diffusion of heat in metals is a fundamental process which is crucial for a variety of applications of metal nanostructures. Surprisingly, however, {\em ultrafast} heat diffusion r…
Size-Dependence of the photothermal response of a single metal nanosphere
Ieng-Wai Un, Yonatan Sivan
We study the thermal response of a single spherical metal nanoparticle to continuous wave illumination as a function of its size. We show that the particle temperature increases no…
Surface second-harmonic from metallic nanoparticle configurations - a transformation optics approach
K. Nireekshan Reddy, Parry Y. Chen, Antonio I. Fernández-Domínguez +1
We study surface second-harmonic generation (SHG) from a singular plasmonic structure consisting of touching metallic wires. We use the technique of transformation optics and relat…
