Sum frequency generation from touching wires: A transformation optics approach
Shimon Elkabetz, K. Nireekshan Reddy, Y. Sivan
We employ transformation optics to study analytically nonlinear wave mixing from a singular geometry of touching plasmonic wires. We obtain the analytic solution of the near-field…
Optimization of second-harmonic generation from touching plasmonic wires
Shimon Elkabetz, K. Nireekshan Reddy, Parry Y. Chen +2
We employ transformation optics to optimize the generic nonlinear wave interaction of second-harmonic generation from a pair of touching metallic wires. We demonstrate a 10 orders…
Recent developments in plasmon-assisted photocatalysis -- a personal perspective
Yonatan Sivan, Yonatan Dubi
It has been known for many years that metallic nanoparticles can catalyse various chemical reactions, both in the dark and under illumination, through different mechanisms. In the…
The thermo-optic nonlinearity of single metal nanoparticles under intense continuous-wave illumination
Ieng Wai Un, Yoatan Sivan
Over the last few decades, extensive previous studies of the nonlinear response of metal nanoparticles report a wide variation of nonlinear coefficients, thus, revealing a highly c…
Effective electron temperature measurement using time-resolved anti-Stokes photoluminescence
Thomas Jollans, Martín Caldarola, Yonatan Sivan +1
Anti-Stokes photoluminescence of metal nanoparticles, in which emitted photons have a higher energy than the incident photons, is an indicator of the temperature prevalent within a…
An efficient solver for the generalized normal modes of non-uniform open optical resonators
Parry Y. Chen, Yonatan Sivan, Egor A. Muljarov
Modal expansion is an attractive technique for solving electromagnetic scattering problems. With the one set of resonator modes, calculated once and for all, any configuration of n…
