Silicon-plus photonics for light manipulation and photodetection

Silicon photonics have been developed very successfully in the past decades. In order to break the limitation of the silicon material for realizing photonic devices, more and more special optical materials are introduced to silicon photonics, and silicon-plus photonics is being developed. In this paper, we give a review on recent progresses of siliconplus photonics for light manipulation and photodetection by introducing metals, germanium, 2D materials, semiconductor nanowires, etc.
