Abstract

Compared with fiber optical current sensors, integrated optical current sensors (IOCS) replace optical fiber with integrated optical waveguide materials, which is suitable for further miniaturization, modularization and low cost of sensors and has become a research hotspot in recent years. In this study, the research progress of IOCS in the world is reported. The IOCS which are realized by the ways of faraday magnet-optic effect and thermal-optic effect are shown respectively. Simultaneously, the performance of IOCS based on different sensing units are compared and their advantages and disadvantages are analyzed. Finally, the current challenge and future development trends of IOCS are summarized.
