Researchers demonstrate first fully solution-processed solid-state polariton laser
Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called polaritons. This makes the platform not only a new type of solution-processed laser but also a powerful way to study nonlinear polariton interactions. The paper is…
Researchers at the University of Turku in Finland have demonstrated a significant breakthrough in laser technology. They have developed a fully solution-processed solid-state organic laser microcavity, a device that operates in the strong light–matter coupling regime. This groundbreaking achievement allows light and matter to form hybrid states called polaritons, which enable the laser to function and study nonlinear polariton interactions.
The fabrication process involves coating each layer from a liquid solution instead of using complex and energy-consuming methods typically employed in solid-state laser manufacture. The mirrors and organic light-emitting layer, both fabricated by spin coating, contribute to the high optical quality necessary for advanced laser physics.
The device's success demonstrates that simple and scalable fabrication can still produce superior optical quality. Hassan Ali Qureshi, a Postdoctoral Researcher from the University of Turku, highlighted the significance of this development, stating that it offers researchers a more accessible way to study these devices, as well as the potential for studying nonlinear polariton behavior through tunable emission patterns.
