Abstract

Sensitivity enhancement in fiber interferometric sensors is achieved by connecting a balanced nonlinear Mach-Zehnder fiber interferometer (MZFI) to the sensing interferometer. Without changing the power of the source, the sensitivity is enhanced by a factor of nonlinear phase shift induced by the optical power in the nonlinear MZFI. The theory is also extended to remote fiber sensing systems.
