Abstract

We demonstrate two types of waveguide structures that optically confine exciton-polaritons in two dimensions and act as polaritonic channels. We show a strong optical confinement in an etched rectangular waveguide that significantly increases the propagation distance of the polaritons and allows to direct them in curved trajectories. Also, we show low-loss optical guiding over a record-high of hundreds of microns, which is combined seamlessly with electrical control of the polaritons, in a strip waveguide formed by electrically conductive and optically transparent strips deposited on top of a planar waveguide. Both structures are scalable and easy to fabricate and offer new possibilities for designing complex polaritonic devices.
