Jamie’s SHG work published in Nano Letters

We demonstrate for the first time, second-harmonic generation (SHG) is allowed through the control of optical modal asymmetry rather than breaking the symmetry of material or geometry. Our idea is realized through a plasmonic two-wire transmission-line. As compared to other SHG using surface plasmon polaritons, our second-harmonic signal remains guided.
