The 3rd West-Lake Photonics Symposium was successfullyheld at the Sir Run Run Shaw Science Building in Yuquan Campus, ZhejiangUniversity (ZJU) from October 25th to 26th, 2018. This symposium was hosted by ZJU’sCollege of Optical Science and Engineering (COSE) and the State Key Laboratoryof Modern Optical Instruments (MOI), organized by the Joint InternationalResearch Laboratory of Photonics (JIRLOP), the International Joint ResearchCenter for Optoelectronic Technology, and the Zhejiang Optical Society, andjointly sponsored by Guangzhou Bo-Guan Limited., Jiangxi Lian-Sheng TechnologyInc and Hangzhou Yong-Can Optoelectronic Technology Limited. The symposium waschaired by Prof. Xi-Cheng Zhang from the University of Rochester and Prof. LIU Xufrom ZJU. Leading Scholars from Sweden, the United States, Taiwan China were invitedto attend this symposium. In this symposium, nine top scholars from the fieldof optoelectronics were invited to report to the plenary session on severalfrontier science research directions, like applications and prospects ofnonlinear optics, advances in nanophotonics, frontier computational imagingtechnology, opportunities and challenges in integrated optoelectronics, andadvanced optoelectronics devices. The symposium attracted more than 150participants. The communicative atmosphere is warm and interactive.

Opening Ceremony
Prof. Xi-Cheng Zhang introduced the results of his group’s recentresearch on generating terahertz radiation through liquid water film in detail.Zhang’s research group helps to complete the scientific goals of generatingterahertz radiation through four states of matter (plasma state, solid state,gaseous state and liquid state). After the report, Prof. Zhang answeredquestions asked by scholars based on specific details of his research withprofound explanation.
Prof. LIU Wenqing from the Anhui Institute of Optics andFine Mechanics of the Chinese Academy of Sciences brought a vivid introductionto the spectroscopy techniques in environmental monitoring, including theapplication of DOAS, LIDAR, TDLAS, FTIR techniques in rapid real-timeatmospheric composition detection. Also, based on the national environmental strategy,LIU proposed the forecast to the future research on optical technology inenvironmental monitoring.
Prof. Lena Wosinska from the Royal Institute of TechnologySweden introduced the concept, development and challenges of flexible opticalnetworks. Prof. Wosinska first explained the manifestation of flexible opticalnetworks in spectrum, space, construction, routing/configuration, and networkmanagement. Then, she concluded the importance of network flexibility and thechallenges it will face in such a high-speed information age.
Based on the theme of brain space informatics, Prof. LUO Qingming,president of Huazhong University of Science and Technology, introduced thevisualization method of the whole brain network based on MOST and BPStechnology in a single neuron resolution. At the end of the speech, LUO pointedout that the brain spatial informatics not only promoted the development ofbrain-like artificial intelligence, itself also relies on the data analysisskill of artificial intelligence, such as machine learning.
Prof. LIU Xu from ZJU introduced the principle of Fourierdomain spatial frequency shift imaging (SFS), and reviewed othersuper-resolution imaging technologies like STED and STORM. Liu ended his speechafter pointing out SFS technology can achieve goals like femtosecond fast imaging,large field of view and high resolution, and has broad application prospects.
Beginning with the principle of laser acceleration, Prof. JILiangliang from the Shanghai Institute of Optics and Fine Mechanics, ChineseAcademy of Sciences, introduced the SULF 10PW and SEL 100PW laser projects inShanghai. He first talked about risks of this project. Then he gave a briefintroduction of the application of this project in vacuum birefringencedetection and its progress. Finally, he emphasized the important meaning of SULFand SEL. In Q&A part, JI patiently answered some questions about vacuumbirefringence detection.
Prof. John Bowers from the University of California, SantaBarbara (UCSB) introduced four stages in the development of integratedoptoelectronics. The first stage is the InP substrate stage. The second stageis the silicon-based photoelectron period. The third stage is the integratedoptics stage. And the fourth stage is epitaxial quantum dot source lasers. Theprofessor highlighted the results of the second and third phases. Due to itslow cost and low waveguide, silicon is widely used in lasers nowadays. Inrecent years, the number of papers on silicon-based photoelectrons published inthe world has also increased exponentially which means that the field ofintegrated optoelectronics still relies on silicon. Besides, UCSB has extensiveresearch in silicon-based optoelectronics and integrated optoelectronics, suchas magneto-optical isolators and ring-resonant coupled lasers.
Professor Din Ping Tsai from Taiwan University introduced hisresearch on the meta surface with passion. Tsai highlighted how his groupsolved the problem of light propagation in meta-lens in reflection andtransmission, and how to achieve the first meta-lens in the world that displaysa panoramic color image. At present, meta-surface is an emerging field inoptical research with many unsolved problems. For example, although many peopledesign meta-lens, there is no systematic design rule. Tsai proposed the rule ofdesigning super-lens, which caused positive response of many participants.
Prof. Scott Carney from the University of Rochester gave aspeech entitled "Lens vs Algorithm, Imaging in the age of computers".Carney used vivid examples to illustrate the application of this idea inoptical coherence tomography (OCT). He believes that this is an era ofcomputational imaging. Data, the combination of image and physics, spectroscopyand structure, sample instruments, all of these can be combined in anextraordinary but understandable way in data processing. In the competitionbetween lens and algorithms, algorithms sometimes win, but more often they worktogether to solve many important and open problems in optical computing imagingand inverse scattering. His speech won warm applause from the audience. In the Q&Asession, one guests asked questions about the details of the interferometricsynthetic aperture microscopy in sharing, and Professor Scott Carney gave adetailed answer.
Plenary Session
The symposium also set a short seminar for specific topicsand poster presentation session. At the seminar, participants gave comprehensivequestions to the nine reports mentioned above. And the speakers answered thesequestions one by one through vivid illustration. In the poster presentationsession, participants picked up posters they were most interested in anddiscussed in detail with the authors standing in front of posters and otherparticipants. The scene was full of academic atmosphere. After expert review,five best posters were voted.
