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: From 1992 to 1997, Petermann et al. at the Tech. Univ. Berlin developed IOESs with segmented modulator electrodes [59–63]. The antenna was located along the waveguide, reducing the equivalent input impedance and improving the match between the dipole antenna and the modulator, as shown in Figure 6(a). The fabricated sensor had a sensitivity of 1 mV/m and a bandwidth of 3 GHz. A sealed sensor was also implemented to detect an E-field in liquid, as shown in Figure 6(b).
