Research

Si-based photonic integrated chips are now widely used for short-reach optical fiber communications in data centers because of a low power consumption and a large capacity with a low cost fabrication. Near-infrared pin photodetectors (PDs) of a Ge layer epitaxially grown on Si is one of the fundamental building blocks in Si photonics. In this study we focus on the fabrication of high crystal quality and low cost production of Ge PDs based on Si technology.
