摘要
Silicon-based photonics technology,which has the DNA of silicon electronics technology,promises to provide a compact photonic integration platform with high integration density,mass-producibility,and excellent cost performance.This technology has been used to develop various photonic devices based on silicon,such as waveguides,filters,and modulators.In addition,germanium photodetectors have been built on a silicon-based photonic platform.These photonic devices have already been monolithically integrated,and a group-IV photonic platform based on silicon and germanium,or standard group-IV materials,has been established.Moreover,photonics–electronics convergence is now being pursued based on this platform.
