Abstract：
 The invention relates to an optical electric integrated sensor for testing strong electric field, belonging to the high-voltage testing technique. Wherein, it uses the chip with electric optical effect to form an optical waveguide with Y-shape fork at two ends and parallel middle part on the surface of chip with titanium metal dispersion method or proton exchange method; two sides of one line of two parallel optical waveguides are mounted with two electrode and two couple polar antennas, which are connected; the inventive optical electric integrated antenna can be used to test the strong electric field (stronger than 100kV/m), while it can test the amplitude, frequency and phase, etc; the invention has few metallic elements to avoid affect tested electric field, to attain high position resolution; the sensor uses optical waveguide to transmit signal, without power source, therefore, it can be used to test high-voltage electric field, with quick response, high sensitivity, and improved test frequency range.
