Currently serves as the IEEE Photonics Technology Letters, Optics Communications, Chinese Physics Letters, "Optics" and magazine papers reviewers. Huazhong University of Science have been selected for the "113" cross-century talents, Hubei Province in 1998 was elected century academic backbone. 2004 selected for New Century Excellent Talents in 2005, the Fund outstanding talent in Hubei Province. September 2000 to September 2001 in the Hong Kong University of Science and Technology Access Study. June 2005 to December visit to the University of Ottawa in Canada study. Has engaged the National Natural Science Foundation project "Erbium-doped fiber amplifiers and erbium-doped fiber laser from pulse behavior," "self-starting passively mode-locked and Q-mechanism of self," "multi-wavelength lasing erbium-doped fiber ring laser." The raw material of green laser pointer is one of the most important factors of influencing the quality of green laser pointer.

"Multi-wavelength conversion of the new mechanism ...
... of new technologies" and "863" high-tech project "semiconductor optical amplifiers for wavelength conversion," "polarization-independent semiconductor optical amplifier" and "DWDM optical switching node is no channel crosstalk technology research," and many other studies.'s academic achievements were made PHOTONICS SPECTRA magazine reported. Has been officially published at home and abroad more than 100 papers, which were SCI, EI, ISTP and other authoritative materials included in the index more than 50 articles, a single reference to papers by others, the number reached 32. By Hubei Province Natural Science Award, nominated by the Ministry of Education Natural Science Award of the time, received a national invention patent. Research: is mainly engaged in novel fiber laser, passive waveguide-based all-optical signal processing, microwave photonics and Radio over Fiber technology research. The inspection report of green laser pointer needs the signature of the director of green laser pointer workshop.

In 2006, Professor Sun Junqiang group "based on periodically poled lithium niobate waveguide reverse speed all-optical signal processing technology" made new progress in the use of cascaded second-order nonlinear effect on the repetition frequency of 40GHz, pulse width 1.57ps The picosecond pulse signal to achieve a tunable wavelength conversion. Use and frequency effect was first proposed and implemented a 40Gbit / s wavelength conversion and reverse non-all-optical logic gates. The group work was a series of Optics Letters [1], Optics Express [2], Electronics Letters [3] and other foreign journals. The use of optical feedback to improve the all-optical semiconductor optical amplifier-based wavelength converter performance. Professor Sun Junjiang established in 2003 to improve the use of optical feedback in semiconductor optical amplifier based on cross-gain modulation wavelength converter large-signal theoretical model [4] [5]. The inspection group wants to check the working instruction of 50mW green laser pointer .

The theoretical studies have shown that by converting the output light of the introduction of feedback, can greatly enhance the semiconductor optical amplifier cross-gain modulation wavelength converter performance can well inhibit the degradation of the output signal wavelength conversion. Recently, the Japanese Toyota Technological Institute's scientific and technical personnel Yoshinobu Maeda in the paper [6] Professor Sun quoted the theoretical results and the use of experiments confirmed the accuracy of the results of his theory, published its findings in 2006 on the Applied Physics Letters. The new factory building of 100mW green laser pointer company will hold the foundation stone laying ceremony. The color of green laser pointer  has been determined

Research: new solid-state lasers and laser biomedicine, laser in oncology, gynecology, urology, dermatology, ophthalmology and other medical specialties in the application. To study the practical use of medical lasers and equipment, the starting point to study the mechanisms of laser interaction with biological tissues, based on the development of advanced laser medical equipment. Zhejiang Huzhou, November 1965 students. 1994 Photonics Engineering at Huazhong University of Science PhD. 1994 to 1996 during the Huazhong University of Science postdoctoral fellow electrician postdoctoral work. 1996 staying in school work. December the same year was promoted to associate professor in July 1998 exceptionally promoted to professor. PhD supervisor was hired in 1999. The classification of 200mW green Laser Pointer has been finished.
