Abstract:

[Objective] Driven by problem- and application-oriented research, this paper analyzes the global competition situation, priority areas and main development trends in the photonic chip field, aiming to provide some insights for decision makers and researchers. [Coverage] This survey contains numerous studies including policy literatures of the leading countries, publications in top-tier international journals, and news reports of enterprise leader. [Methods] Combined with the policy literatures, scientific literatures and news items in the photonic chip field, advanced academic and industrial progresses of the photonic chip are summarized based on the meta-analysis method and analytic hierarchy process. [Results] This paper analyzes the R&D policies of the United States, Europe, Japan and China, summarizes the research issues and relevant important progresses, and briefly describes the main development trends at present. [Limitations] The photonic chip field involves numerous research contents, this paper only describes the research focuses and research trends of the photonic chip in information technology landscape at a macroscopic level, related research advances in other subdivisions may not be fully covered in this paper. [Conclusions] The excellent characteristics of the photonic chip makes it one of the potential disruptive technologies in the “post-Moore era” of the global integrated circuit industry. A key industry explosion period of photonic chip is forthcoming in the near future, but we still need to solve many basic research problems and technological challenges to increase industrial competitiveness.

Key words: photonic chip, photonic integrated circuit, global competition situation, research focus, research trend
