특허 및 국가연구개발 현황 분석을 통한 테라비트급 광통신 부품 R&D 방향성 연구

In this study, we investigated patent indexes of technology, market, and concentration and compared the results with those of national R&D projects. We studied terabit optical communication components, which are the core infrastructure for data centers and edge-clouds, among 38 future leading items of the national R&D industry. In this study, we try to understand the national R&D direction for this technology by analyzing the patents and R&D projects trends. The patent analysis suggested that the technology and market indexes of the patents for the Korean industry are lower than those of leading countries. The patent concentration index indicates weak competition market in this area. Based on the results for national R&D projects, we observed that the Korean government supports basic and development-level research. Finally, we recommend that the Korean government should support basic and applied research in terabit optical communication components for the national industrial competitiveness.
