Plasmonic waveguides - a step closer to integrated nonlinear nanophotonics architectures

Integrated nonlinear optical devices are one of the fundamental building blocks of any modern optical integrated circuits, especially those operating in the quantum optical regime. However, dielectric photonics platforms are limited by diffraction, hence they are not compact enough to make these devices resource and energy efficient. In order to operate beyond the diffraction limit, these devices could implement plasmonic waveguide-based architectures. In this presentation we show how novel and superior performing plasmonic waveguide configurations could be the next step toward compact and energy efficient nonlinear optical devices. Furthermore, we show how these plasmonic waveguides can be fabricated and integrated with modern integrated dielectric waveguides.
