Abstract
We demonstrate a highly-sensitive current sensor by packaging a single taper-based modal interferometer into a copper tube that is filled with alcohol and surrounded with chrome-nickel wire. As the flowing current in the chrome-nickel wire is changed, the interference spectrum varies accordingly with sensitivity as high as 1014.5 nm/A2 . Our results are promising for the current sensing and the electric-tunable filtering.
