Abstract

We develop an electric field sensor array based on optical fiber interrogation with electro-optic crystals to measure high energy electromagnetic pulses. The D-shaped optical fiber used in this work provides the platform for resonant coupling with multiple electro-optic crystals to allow an array of sensing points on a single strand of optical fiber. Because of its uniquely small size, this sensor array is suitable for performing electric-field analysis at multiple points within an electronic device due to its flexibility and dielectric composition. Using Lithium Niobate and Potassium Titanyl Phosphate crystals, the sensor array in this work is sensitive to fields as low as 100 V/m.
