Abstract

This paper investigates the principle of interference between modes in fiber, and gives the relationship between interference of LP₀₁ and LP₁₁^even mode and the axial length variety in ideal fiber. A novel scheme of voltage transducer based on interference between modes is brought out. A PANDA fiber wrapped quartz crystal sandwiched with two pieces of metal electrodes works as sensing interferometer. When voltage is applied on the metal electrode, circumference of quartz crystal will change. This can modulate the light path difference of LP₀₁ and LP₁₁^even mode in fiber. A receiving interferometer balances the light path difference with a fiber wrapped piezoelectric ceramics and a phase tracer. Control voltage of the receiving interferometer is output signal of the transducer. Simulation result and adjusting method of dynamic range is given in the paper. It can provide a new method for designing voltage transducers.
