The brief introduction of the three winners of the Nobel Prize in Physics in 2009 and their inventions (optical fiber and charge coupled device(CCD)) are given. The structures, working principles and applications of the optical fiber and CCD have been described. The Nobel Prize in Physics in the hundred years not only enhanced our understanding to the world and the universe (such as quantum theory, relativity and the model of universe), but also changed our daily life (such as X-ray, radio technology, discovery and research of the superconductivity, discovery and research of the cosmic inicrowave background radiation). Optical fiber and CCD have been joined our daily life and will play very important role.
