Abstract

A key point of exciton-polaritons is the real-time potential energy controllability due to the interaction from excionic components. Although wide-bandgap semiconductors can form room-temperature polaritons, lateral localizations (disorders) of planar cavities still obstruct the establishment of ballistic extensions of polariton condensates. Here, we propose a novel room-temperature polariton platform with ultralow disorders enabling to ballistic extensions. Hexagonal GaN wires moderates disorders in both photon-perspective and exciton-perspective. This structure allow us to actively control the potential energy and its landscape of room-temperature polartion condensate for the ballistic propagation. The correlation between real- and momentum-space provides strong indication of ballistic propagations.
