Optics is an ancient and vibrant subject with a rich his-tory of thousands of years.Since Maxwell discovered that light is an electromagnetic wave,optics has always been accompanied by electricity.Optics and opto-electronics play a vital role in many key fields related to the devel-opment and progress of mankind,such as energy,infor-mation,internet,astronomy,and medicine,etc.Many large-scale scientific projects,ranging from laser nuclear fusion to gravitational wave detection,from large-aperture telescopes to lithography equipment,are mainly based on opto-electronic science.
