Silicon Photonics is a highly active research field which aims at replacing electronic signals for data transfer between chips and within a chip by optical signals. Key components for optical data transfer are efficient light sources that can be monolithically integrated into silicon digital circuits with standard silicon device technologies. A promising approach to achieve this goal is the use of silicon-germanium quantum dots embedded into optical cavities. In this video the physics and fabrication steps of a photonic crystal cavity with an embedded single silicon-germanium (SiGe) quantum dot are explained.
