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.

Mentions: The IOES is able to effectively respond to a standard lightning wave (1.2/50 μs) and an EMP with an ns-order rise time [85]. The performance of the adopted sensor is adequate for measuring the E-field in air gap discharges. After calibrating the sensor, a rod-plane discharge experiment under positive lightning impulse was designed and is shown in Figure 24. A rod with a semi-spherical tip with a 1 cm radius was hung at a height of 1 m above a well-grounded plane. The E-field sensors were placed in the gap at distances ranging from 30 cm to 70 cm above the plane.
