Thedirectionalsensitivityofnematicliquidcrystalin- filtrated polarization-maintaining photonic crystal fiber to an ex- ternally applied electricfield is evaluated for two-dimensional elec- tric field sensing. Selectively infiltrated and infiltration length op- timized polarization-maintaining photonic crystal fiber is used as a probe. Using a polarimetric scheme, the polarized transmission properties of the infiltrated fiber are evaluated in terms of the ori- entation of thefiber polarization axis in anelectricfield. It isshown that the sensor has varying sensitivity to electric fields oriented at different angles with respect to thefiber polarization axis. The pro- posed low-cost all-fiber sensor can be used for two-dimensional di- rectional electric field sensing.
