measurement of strain and temperature with insensitivity to external refractive index. This …

A compact all-fiber magnetic field sensor is achieved by using Mach-Zehnder interferometer
based on the hollow optical fiber (HOF) and the magnetic fluid (MF). The HOF is sandwiched …

Abstract An open-cavity Mach-Zehnder interferometer (MZI) liquid refractive index (RI)
sensor based on multimode interference (MMI) coupling is proposed and demonstrated. The …

An all-fiber and low-cost strain and temperature sensor realized by the cascaded FPI/LPFG
interferometer was developed. This device consists of an input single mode fiber (SMF) …

A novel microfiber sensor is proposed and demonstrated based on a singlemode-tapered
hollow core-singlemode (STHS) fiber structure. Experimentally a STHS with taper waist …

The temperature influence to a refractive index (RI) sensor based on a macro-bending
tapered plastic optical fiber (POF) was investigated experimentally. The total temperature …

In this work an Intrinsic Fabry-Perot Interferometer (IFPI) based on an air-microcavity is
presented. Here the air microcavity, with silica walls, is formed at a segment of a hollow core …

A highly sensitive curvature and displacement sensing arrangement based on an all optical
fiber micro Fabry–Perot Interferometer (MFPI) is presented. Here, the MFPI spectral fringes …
