ABSTRACT
The measurement of intense E-fields is a fundamental need in various research areas. Integrated optical E-field sensors (IOESs) have important advantages and are potentially suitable for intense E-field detection. This paper comprehensively reviews the development and applications of several types of IOESs over the last 30 years, including the Mach-Zehnder interferometer (MZI), coupler interferometer (CI) and common path interferometer (CPI). The features of the different types of IOESs are compared, showing that the MZI has higher sensitivity, the CI has a controllable optical bias, and the CPI has better temperature stability. More specifically, the improvement work of applying IOESs to intense E-field measurement is illustrated. Finally, typical uses of IOESs in the measurement of intense E-fields are demonstrated, including application areas such as E-fields with different frequency ranges in high-voltage engineering, simulated nuclear electromagnetic pulse in high-power electromagnetic pulses, and ion-accelerating field in high-energy physics.

f1-sensors-12-11406: Intense E-field measurement in (a) a 1 m rod-plane air gap; (b) a window of an ultra-high voltage transmission tower; and (c) a NEMP simulator.

Mentions: The E-field is a fundamental physical parameter that describes electromagnetic phenomena, and measurement of these phenomena is a basic tool for research in various fields of science and technology. First, in high-voltage engineering studies, various phenomena and problems are attributed to the presence of an E-field, e.g., corona discharge, partial discharge, gap breakdown, and the electromagnetic environment. The acquisition of a direct current (DC) field distribution is important in the optimization of a high voltage direct current converter station [1]. An alternating current (AC) power frequency E-field measurement near the surface of an overhead line is essential to the study of electromagnetic environmental problems [2]. Microsecond-order transient E-field detection is necessary for understanding the physical process of long air gap discharge and lightning [3], shown in Figure 1(a) and Figure 1(b). Nanosecond-order transient E-field measurement is significant for the investigation of very fast transient overvoltage (VFTO) in a gas insulation substation (GIS) [4].
