This paper presents a means for creating optical fiber sensors that are capable of detecting electric fields. This novel E-field sensor is formed as part of a contiguous fiber resulting in a flexible and small cross-section device that could be embedded into electronic circuitry. The sensor is formed by partially etching out the core of a D-shaped optical fiber and depositing an electro-optic polymer. Using PMMA and DR1 for proof of concept, we demonstrate the operation of the first in-fiber hybrid waveguide electric field sensor with a sensitivity of less than 100 V/m at a frequency of 2.9 GHz. Sensors optimized for low loss (~1dB) have an estimated E&pgr; of 222 MV/m. A sensor with an E&pgr; of 60 MV/m is also demonstrated with an insertion loss of 14.4 dB.
