2020 West-Lake Photonics Symposium was held on November 28, 2020 at ZJU’s International Campus in Haining. The opening ceremony was presided over by Professor Dai Daoxin, Vice Dean of the College of Optical Science and Engineering, and Professor Liu Xu, Secretary-General of the Chinese Optical Society, delivered an opening speech.

Affected by the epidemic, this conference was carried out in a combined online and offline manner. A total of 10 top scholars from the field of optoelectronics were invited to give a report on quantum optics, metasurfaces and metamaterials, computational spectroscopy and super-resolution imaging, two-dimensional material, silicon-based optoelectronic devices. The conference attracted more than four thousand teachers and students to listen online.
