Findings. The structure and operation principles of high frequency electric fields intensity sensor on the base of slot waveguides with vertical and horizontal slots filled with electro-optical polymer are proposed. Sensor makes it possible measuring the variable electric fields with frequencies up to 10 MHz. The sensor sensitivity order is of 30 V/m.
Application field of research. Determination of fire-dangerous and injurious factors of electric field during emergencies elimination.
We consider the structure of a high-frequency external electric field sensor based on microring resonators using waveguides with two horizontal or vertical slots filled with an electro-optical polymer. The method of lines is used to calculate the propagation constants and mode field distributions of such waveguides. It is shown that double-slot waveguides filled with an electro-optical polymer exhibit higher optical radiation intensity in the slot region compared to single-slot waveguides, which makes it possible to increase the sensor sensitivity. The distances between the slots and the values of their widths at which a maximum sensor sensitivity is achieved are determined. The sensor allows alternating electric fields with frequencies up to 10 GHz to be measured in the range of 100−16 × 106 V m−1 with an accuracy of 150 V m−1.
