This work presents the development and characterization of an optical fiber current transducer based on lossy mode resonances (LMRs) to work in high voltage networks. A multilayer structure was created in order to be able to shift the LMR by an electro-optic material deposited in the middle of two electrodes. The optical resonance has a displacement range of 200 nm on its TM component, what makes this device suitable for current sensing. Furthermore, dip coating of polyvinylidene difluoride has enhanced the nanofilm uniformity with respect to previous devices.
