In an article recently published in the open-access journal Light: Science & Applications, researchers constructed a specific GeSn-on-insulator (GeSnOI) stack with the help of stressor layers as dielectric optical claddings. They also demonstrated that GeSnOI is suitable for monolithic integration of planar Group-IV semiconductor lasers on photonic platforms in the near- and mid-infrared wavelength range.
