Abstract
The possibility of increasing the sensitivity of measurement transducer of the high frequency external electric field is analyzed. The increasing is possible by using the ring waveguides with two vertical and horizontal slots filled with electro-optic polymer. The structure of the measurement transducer is considered. In waveguides with two slots the intensity of propagating optical radiation in the slot region is higher than in single slot waveguides. The values of optimal slot width and separation are determined, which make it possible to achieve the maximal transducer sensitivity. The measurement transducer allows measuring the alternating electric fields with the frequency from 0 to 10 GHz in the range from 150 to 16·106 V/m with the resolution up to 150 V/m due to using the active organic polymer SEO125 and double slot waveguide. The measurement transducer can be applied for detecting the high-frequency waves electromagnetic pulses, analyses of external electromagnetic interference and diagnosis of high-frequency electronic circuits.
