On-chip modular hybrid plasmonics
Dr. Alessandro Tuniz, University of Sydney, Australia
Leuchs-Russell Auditorium, A.1.500, Staudtstr. 2
In this talk I will discuss recent experimental progress in the development of modular, compact, and efficient on-chip hybrid plasmonic functionality. This approach can transform off-the-shelf silicon-on-insulator waveguides into efficient plasmonic nano-concentrators, which I use to demonstrate on-chip plasmonic second harmonic generation enhancement. Time permitting, I will also discuss novel compact dielectric-plasmonic coupler designs, and present new experiments which showcase the properties of plasmonic Eigenmodes near their non-Hermitian exceptional points.
