Application of two-mode fiber in voltage sensor

Abstract

A new mode pattern's demodulation technique is put forward. Researches of experiment and theory show that the coupling efficiency of two kinds of different fibers depends on the relative offset between the two fibers when the core diameter of the information pick-up fiber is a little smaller than the major semi-axes of the elliptical-core two-mode fiber. Especially, when the relative offset 'delta' is about 1, fusing splice coupling efficiency reaches peak value. Furthermore, based on the new demodulation scheme, the sine voltage signal applied on the piezoelectric lead zirconate titanate (PZT) is obtained and the detection precision of the system is within +-0.2% when the voltage changes between 0.1 and 20 V.
