Abstract

We have developed and tested fiber optic electric and magnetic field sensors for ultra wideband (UWB) applications. The sensors are based on nonlinear effects in electro-optic (EO) and magneto-optic (MO) crystals. Unlike conventional antenna-based probes, EO and MO sensors are composed of all-dielectric materials and do not perturb the very fields that they measure. The sensors are small in size (less than 5mm in diameter), allowing them to be used in confined spaces and can be used with over 50 meters of optical fibers. These features make the sensor very well-suited for UWB applications and attractive for potential commercial use.
