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: IOESs can be classified into three types according to differences in their waveguide structure and in their operating principle: the Mach-Zehnder Interferometer (MZI), the Coupler Interferometer (CI), and the Common Path Interferometer (CPI). The measurement system is illustrated schematically in Figure 3(a). The linear polarized light generated by the laser source is transported to the sensor through a polarization-maintaining fiber. The optical signal is phase-modulated or polarization-state-modulated by the E-field as it passes through the waveguide. For the MZI or CI types, the phase modulation is transferred to intensity modulation at the output end of the waveguide. For the CPI type, the polarization-state modulation is changed to intensity modulation by the analyzer. The intensity signal is then delivered to the photo-electric converter by a single-mode fiber, where the optical signal is converted into an electrical signal. The sensor is situated in an intense electromagnetic environment, whereas the electronic devices are located in an electromagnetic shielding environment. The effective electrical isolation could be provided by the input/output fiber.
