1.Joint International Research Laboratory of Photonics

Joint International Research Laboratory of Photonics (JIRLOP) was established in 2015, which was approved by the Ministry of Education of China. JIRLOP is a collective force of the world-class research teams on photonics from Zhejiang University (ZJU), University of Rochester (UR) and Royal Institute of Technology (KTH). Being an independent research center consisting of laboratory council, academic advisory committee and principal investigators, the vision of JIRLOP is becoming a world-leading laboratory of photonics pursuing discoveries in the areas of photonic devices and advanced photonic instrumentation.

JIRLOP has committed to boost international collaboration. The laboratory has been collaborating closely with research institutes from KTH, UR, and Ghent University to participate in international research in the following areas: 

（1） Photonic devices,

（2） Integrated photonic devices,

（3） Advanced photonic instrumentation.

In September 2019, College of Optical Science and Engineering of Zhejiang University and KTH signed an international master's double degree framework cooperation agreement, which will further carry out international master's education cooperation in the field of optical engineering, and cultivate outstanding talents with international vision and innovative thinking.

2.ZJU-TU/e Joint Research Institute of Design, Optoelectronics and Sensing

ZJU-TU/e Joint Research Institute of Design, Optoelectronics and Sensing (IDEAS) was established in 2019 to enhance the collaboration among TU/e, ZJU and the National Engineering Research Center of Optical Instrumentation. IDEAS carries out a wide range of joint research/exchange projects in optoelectronics and sensing technology and its application fields (including integrated photonics, nanophotonics, biomedical optics and optical/THZ sensing technology), sharing professional technical knowledge, infrastructure and equipment to jointly develop the institute. IDEAS Actively invites industrial partners (such as Philips, Soxh, Alibaba, Huawei, etc.) to participate in project cooperative research and development to keep the level of joint research at the forefront of international photoelectric and sensor technology application research. Through the establishment of a committee, in-depth research cooperation, joint publication of research results, and exchange of researchers and graduates, IDEAS further cultivates and promotes the close cooperation between the two universities. At the same time, it will host international academic conferences to increase the influence of both parties.

3.Sino-Swedish Joint Research Center of Photonics

Sino-Swedish Joint Research Center of Photonics (JORCEP) was founded in October 2003 to enhance the collaboration between the Royal Institute of Technology and Lund University in Sweden and Zhejiang University in China. The center supports the bi-lateral cooperation research and education in the field of photonics, including joint academic researches, joint-PhD education and international Master of Science program in Photonics. At JORCEP, both fundamental applied researches are carried out for scientific challenges and industry demands. The main research directions of JORCEP include optical metamaterials, integrated photonics, optical networking, and biophotonics. The international visibility of JORCEP has been very significant. On November 11, 2010, JORCEP was visited by the delegation from the Royal Swedish Academy of Engineering Sciences (IVA) under the surveillance of His Majesty the King of Sweden. A number of graduates was co-cultivated by JORCEP.

4.The International Laboratory of Hamamatsu Photonics

The International Laboratory of Hamamatsu Photonics was jointly established by Hamamatsu Photonics K.K. of Japan and the Department of Optical Engineering of Zhejiang University in 1995. The laboratory focuses on the research areas of photonic controls, photodetection and bio-x imaging. The research directions include ultra-weak photonics in biological systems; Transient bio-photonics; high-resolution detection of Positron Emission Tomography(PET); forward and inverse problem in bio-imaging; Medical image technology; The laboratory enhances international cooperations greatly and has built up strong worldwide connections with Yale University, Rochester University, Hamamatsu Photonics K.K., Hong Kong University of Science and Technology, University of Florida, etc. A number of graduates were co-cultivated by the laboratory.
