Preface to Special Issue on Highly Functionalized Silicon Photonics by Hybrid-Material Integration

Abstract

This issue features hybrid integrated silicon photonic that could break the conventional limits of monolithic silicon integration. Recent high-capacity internet and fast data processing demand the speed and low-energy consumption of optical devices. It is now not an easy task to satisfy these demands only with silicon. Emerging hybrid-integration technologies with materials such as InP, Ge, Graphen, Magneto-optical material, nanophotonic elements, and polymers will break the limit of current silicon photonics.
