Abstract

The invention discloses an integrated optical two-dimensional electric field sensor and measurement system. The electric field sensor comprises a lithium niobate substrate, optical waveguides and two sets of dipole antennas. The two parallel optical waveguides are formed on the surface of a lithium niobate crystal through titanium diffusion. An oxidation layer is deposited on the surface of the lithium niobate substrate. The dipole antennas are laid on the two optical waveguide arms respectively. The polarization directions of the two sets of dipole antennas are orthogonal. Thus measurement of a two-dimensional electric field is achieved. The direction, amplitude and frequency information of the electric field are measured. The system integrates the two-dimensional electric field measurement function onto the lithium niobate substrate. The system is compact in structure, small in size, simple in technique, high in measurement precision, and easy for processing.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to an integrated optical two-dimensional electric field sensor and a measurement system. Background technique [0002] Measuring the distribution of the electric field plays an important guiding role in the research of high-voltage electrical engineering, such as corona discharge, gap discharge and high-power electromagnetic pulse detection, such as nuclear magnetic burst pulse. The detection of microsecond-level transient pulses in high-voltage electricity is conducive to understanding the physical mechanism of long-gap discharges; the amplitude and frequency information of high-power electromagnetic pulses can be used to analyze and evaluate the harm caused by them, thereby providing reference for the protection of electronic equipment. Traditional electric field measurement systems use electrically active metal sensors. However, the metal parts of the electri...
