Abstract

We report on an on-chip routing device for propagating condensates of exciton-polaritons. This counter-directional coupler implements signal control by a photonic microdisk potential, which couples two lithographically defined waveguides and reverses the condensate's propagation direction. By varying the structural sizes, we utilize the conjunction of the different dimensionalities to additionally evidence the functionality of a polaritonic resonant tunnel diode. Furthermore, we show the ultra fast time dynamics of the device via ps-resolved streak camera measurements. This scalable, all-directional coupler element is a central building block for compact non-linear on-chip photonic architectures.
