Paper Abstract
We report an electric field sensor based on a charged microparticle that is optically trapped, and moved to and
fro, inside a hollow-core photonic crystal fibre (PCF). Transverse electric fields displace the particle, altering
the transmitted optical power. The transmission change is found to be linear with fields in the 0.1-50 kV/m
range, with a flat frequency response from 0.01 to ~1 kHz. In a first test, the field pattern near a multi-element
electrode was resolved with a spatial resolution of 1 mm. This unique "flying particle" sensor allows electric
field mapping over long distances (the lowest loss hollow core PCF has a 3 dB length of ~3 km) and is
suitable for inaccessible or harsh environments.
