N2 - This paper presents an optical electric field sensor (OEFS) based on evanescent field characteristics of micro-nano fiber (MNF) and electro-optic effect of electro-optical polymer to solve the problem of large size, large influence on measuring field and low sensitivity in the traditional electric field sensors. The sensor body is fabricated using a MNF coating Special electro-optic polymer. In the case of MNF with a diameter of several microns, most of the energy in the optical fiber exists in the electro-optic polymer in the form of evanescent field. The refractive index of electro-optic polymers changes with small change of external electric field, which results in the change of energy intensity and evanescent depth of evanescent field, and then affects the intensity of output light of sensor. By detecting the output light intensity of the sensor, the information of the spatial electric field can be obtained. At the end of the paper, the feasibility of the sensor scheme is verified by simulation and experiment.
