We demonstrate the operation of an in-fiber electric field sensor. The sensor is fabricated with selective chemical etching of the core of a D-shaped optical fiber followed by the deposition of an electro-optic polymer (PMMA∕DR1), which forms a hybrid core. The device demonstrates electromagnetic field sensitivity less than 100 V / m at a frequency of 2.9   GHz . E π is estimated to be 60 MV / m with an insertion loss of 14.4   dB .
