tapered fiber mach zehnder Interferometer for simultaneous measurement of refractive index and temperature
Applied Physics Letters, 2009Co-Authors: Liqiu Men, Kevin Sooley, Quiying ChenAbstract:An approach to achieve simultaneous measurement of refractive index and temperature is proposed by using a Mach–Zehnder Interferometer realized on tapered single-mode optical fiber. The attenuation peak wavelength of the interference with specific order in the transmission spectrum shifts with changes in the environmental refractive index and temperature. By utilizing S-band and C/L-band light sources, simultaneous discrimination of refractive index and temperature with the tapered fiber Mach–Zehnder Interferometer is demonstrated with the corresponding sensitivities of −23.188 nm/RIU (refractive index unit) and 0.071 nm/ °C, and −26.087 nm/RIU (blueshift) and 0.077 nm/°C (redshift) for the interference orders of 169 and 144, respectively.

highly sensitive gas pressure sensor using twin core fiber based in line mach zehnder Interferometer
Optics Express, 2015Co-Authors: Zhengyong Li, Changrui Liao, Yiping Wang, Lei Xu, Dongning Wang, Xiaopeng Dong, Qiao Wang, Kaiming Yang, Jiangtao ZhouAbstract:A Mach-Zehnder Interferometer based on a twin-core fiber was proposed and experimentally demonstrated for gas pressure measurements. The in-line Mach-Zehnder Interferometer was fabricated by splicing a short section of twin-core fiber between two single mode fibers. A micro-channel was created to form an Interferometer arm by use of a femtosecond laser to drill through one core of the twin-core fiber. The other core of the fiber was remained as the reference arm. Such a Mach-Zehnder Interferometer exhibited a high gas pressure sensitivity of −9.6 nm/MPa and a low temperature cross-sensitivity of 4.4 KPa/°C. Moreover, ultra-compact device size and all-fiber configuration make it very suitable for highly-sensitive gas pressure sensing in harsh environments.

Asymmetrical in-fiber Mach-Zehnder Interferometer for curvature measurement
Optics Express, 2015Co-Authors: Bing Sun, Yinjie Liu, Yijian Huang, Changrui Liao, Guolu Yin, Shen Liu, Jun He, Chao Wang, Jing Zhao, Jian TangAbstract:We demonstrated a compact and highly-sensitive curvature sensor based on a Mach-Zehnder Interferometer created in a photonic crystal fiber. Such a Mach-Zehnder Interferometer consisted of a peanut-like section and an abrupt taper achieved by use of an optimized electrical arc discharge technique, where only one dominating cladding mode was excited and interfered with the fundamental mode. The unique structure exhibited a high curvature sensitivity of 50.5 nm/m-1 within a range from 0 to 2.8 m-1, which made it suitable for high-sensitivity curvature sensing in harsh environments. Moreover, it also exhibited a temperature sensitivity of 11.7 pm/°C.

Integrated optical dual Mach-Zehnder Interferometer sensor
Sensors and Actuators B: Chemical, 2001Co-Authors: K. Kawaguchi, James S. WilkinsonAbstract:A fibre-pigtailed dual-sensitivity integrated optical Mach-Zehnder Interferometer sensor chip for liquid analytes is described. Thin overlays of Ta/sub 2/O/sub 5/ and reference structures have been integrated to enhance sensitivity and compensate for drift and attenuation.
