Abstract
This paper proposes a no-core-single-mode-no-core Mach–Zehnder fiber sensor. In this
sensor, two no-core fibers serve as input and output couplers, and the
middle single-mode fiber serves as a sensing arm. Using finite element
simulation and theoretical analysis, the optimal length of the
couplers and the sensing arm are determined. High-order modes excited
by no-core optical fiber propagate through the cladding of the
single-mode fiber, which is affected by the ambient temperature and
applied force. The trough of different interference orders of the
transmission spectrum is selected as a research object to realize the
measurement of curvature and temperature, strain and temperature with
the sensing matrix.
