InP-based membrane lasers have attracted much attention as high-speed and high-efficiency light sources for future optical data communications. In pursuit of their ultimate performance, advanced thermal management will be indispensable. In this work, we used transfer printing and report the fabrication of InP-based membrane lasers directly integrated on a diamond substrate, which has the highest thermal conductivity among any solid materials.
