Wei-Rong Zhuo A Mach–Zehnder Interferometer Based on an Ultracompact Leaky-Guided Liquid Core
Wei-Rong Zhuo;Tai-Kai Liu;Cheng-Ling Lee

We proposed a novel sensor based on an ultracompact leaky-guided liquid-core fiber Mach-Zehnder interferometer (LLCFMZI) for high modulation of interference spectra. The structure is based on a micron-sized hollow-core fiber (HCF) splicing a tilt endface single-mode fiber (SMF) to create a miniature oblique gap for effective access of different liquids.

Chi-Shiang Chen Fiber Michelson Interferometer Temperature Sensor based on a Liquid-core Fiber
Chi-Shiang Chen;Sheng-Yun Cho;Cheng-Ling Lee

This study presents a highly sensitive liquid-core fiber Michelson interferometer (LCFMI) for sensing temperature (T). The structure is based on single-mode fiber (SMF) fusion splicing a micron-sized liquid-core fiber (LCF) whose volume of liquid is only a few picoliters.

Chih-Chuan Chiu Dynamic vibration sensor based on fiber Bragg grating
Chih-Chuan Chiu;Cheng-Yu Lin;Wen-Fung Liu;Yi-Lin Yu

This paper shows the fiber grating sensor for detecting acoustic vibration signals. We design two kinds of sensing structures and experimentally demonstrate to confirm the sensing performance in different frequency bands. The wavelet transform is used for analyzing the variety of the non-stationary signal.

Yu-Tong Lee An Electric Field Sensor Based on A Tilted Fiber Bragg Grating Combined with The Liquid Crystal
Yu-Tong Lee;Wen-Fung Liu;Hung-Ying Chang;Ming-Yu Fu

This paper proposed a novel electric-field fiber sensor composed of a tilted fiber grating (TFBG) and the liquid crystal. Due to that TFBG is insensitive to electric field changes, the index change of TFBG’s cladding layer can be used for indirectly measuring the testing electric field. The variation of the electric-field intensity will create the index change of the liquid crystal and then to cause the loss-dip wavelength shift of the TFBG. By means of monitoring the wavelength shift of spectrum loss-dip to obtain the the testing electric field intensity.

Chia-Tse Hsu Optical Fiber Grating Humidity Sensor Based on Calcium Chloride
Chia-Tse Hsu;Cheng-Yu Lin;Wen-Fung Liu;Hung-Ying Chang;Yi-Lin Yu

In this paper we propose a humidity fiber sensor by using a tapered superstructure fiber grating coated on the thin-film of calcium chloride. The operation mechanism is based on the humidity to cause the index change of calcium chloride and then to result in the grating spectrum variation.
