Sensor of high frequency electric fields intensity on the base of slot waveguides with electro-optic polymer filling

Abstract

Purpose. Development of the structure and operation principles of high frequency electric fields intensity optical sensor. Methods. Method of lines was used for calculation of propagation constants and mode electric fields distribution of strip waveguides with vertical and horizontal slots filled with electro-optical polymer SEO125. 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.
