Since returning to China, he has published more than 30 academic papers1in internationally renowned academic journals (including 4 phys.rev.lett, 2 1 appl.phys.lett, 12 opt.lett, 15 Opt). Express and 23 phys.rev applied for more than 30 patents at home and abroad. A number of research results with important international influence have been achieved. Solve the key technical problems such as single photon measurement and control, coding and polarization sensitivity for long-distance transmission? A new single photon detector has been developed. Its key technical indicators are better than the best international reports; Sagnac time-sharing phase coding and decoding technology is proposed and implemented. The Roadmap of Quantum Information Science and Technology compiled by Los Alamos National Laboratory is cited as one of the representative schemes. The frequency conversion of single photon level is realized; Get the highest quantum conversion efficiency and the lowest conversion noise in the world so far? It has become one of the effective technical ways of infrared single photon measurement and control; Long-term stable single-photon polarization coding, which was previously considered as a challenging topic by a quantum information technology roadmap, was first realized in long-distance optical fibers? Complete a stable long-distance quantum secure communication system. Luminescence based on nano-diamond color center? A new method to obtain long-term stable single photon emission at room temperature? The article in Science Review thinks that this is a practical single photon source, which is expected to be applied to quantum secure communication between the earth and satellites. A series of new physical effects have been discovered in ultrafast photon manipulation experiments and developed into new technologies. The experiment proves the new physical mechanism of modulation parametric amplification, and develops a new technology of ultrafast laser pulse modulation upconversion parametric amplification. Up-conversion amplification pulse output at least one order of magnitude larger than that of conventional optical parametric amplification can be obtained. Many new types of ultrashort laser pulses and their spatio-temporal local photoelasticity and spatio-temporal shaping control were discovered. Two new control methods are proposed to realize the automatic stabilization of carrier envelope phase. A new concept of precise control of ultrafast light field enhanced by surface plasmon resonance and a new method of generating ultraviolet femtosecond optical frequency comb are proposed. With the development of precision control technology, many new ultrafast photon sources have been realized. Achieve high repetition rate ultrashort pulse amplification with an average power of 262W? A high-power driving source for generating ultraviolet frequency comb is developed.
As the project leader, he undertook the construction of several national and provincial key fund projects? Among them, the National Natural Science Foundation's Outstanding Youth Fund 1 item and the Natural Science Foundation's four general projects; 3 "973 Plan" projects; Shanghai Key Discipline Project1; 1 Shanghai Excellent Academic Leaders Project; 2 international cooperation projects of Shanghai Science and Technology Commission; Four key projects of Shanghai Science and Technology Commission. Was rated as excellent in the acceptance of several projects? The project under study is progressing smoothly. Accumulated 24 doctoral students; Among them, 9 people have obtained doctoral degrees. The students have won many international and provincial and ministerial awards; For example: National Top 100 Excellent Doctoral Thesis Nomination Award (1 person-time), Shanghai Graduate Excellent Achievement Award (4 person-times), Rao Yutai First Prize in Basic Optics (1 person-time), Rao Yutai Excellence Award in Basic Optics (1 person-time) and Einstein Award (1 person-time). Mayor Award of Shanghai Youth Science and Technology Innovation (1 person-time) and Second Prize of Shanghai Science and Technology Progress (1 person-time) were selected to attend the 58th Lindau Nobel Prize Winners' Conference in Germany (3 persons-time).
