During the meeting between the director of Institute of Solid State Physics of University of Latvia (ISSP UL) Dr. Andris Anspoks, representative of National Sun Yat-sen University (NSYSU) Prof. Mitch Chou and representative of the Taipei Mission in Latvia Andrew Lee, four scientific directions were crystallized in which Latvia and Taiwan could go into joint cooperation. Therefore, on June 15 and 16, the third Bilateral Scientific Workshop between ISSP UL and NSYSU researchers was organized. Four different sessions were held – Polymer photonics, Biomedical technologies, Photonic Integration Devices and Fiber-related applications, Thin film materials and technologies. The hybrid format workshop demands direct contact approach, so each session was represented by one to three researchers from each institution to achieve the best communication opportunities. At the end of the workshop, the following action steps were discussed to promote cooperation. One of them was the NSYSU’s visit to ISSP UL after the summer when the restrictions imposed by the Covid-19 epidemic will hopefully have eased in both countries.
