Abstract: Combined with the construction of postgraduate courses such as optical system

design，advanced optical communication technology and advanced quantum mechanics，the team has

strengthened the concept of pro- moting education through scientific research，brought the frontier

research projects of optics into postgraduate teach- ing and research training. The team has

carried out innovative teaching practice focusing on theoretical basis， strengthening

simulation practice and integrating science and education. Through the challenging practice

cases of basic optics，modern optics and comprehensive application，the basic theory and simulation

practice，the scientific research and engineering application are combined to strengthen the

cultivation of graduate students ' innovative practice ability and scientific exploration ability.

Key words: space optical communication, three-dimensional visualization, simulation practice, engineering application, scientific exploration
