Simple Interrogator for optical fiber-based white light Fabry–Perot interferometers
Optics Letters, 2017Co-Authors: Zhihao Yu, Zhipeng Tian, Anbo WangAbstract:In this Letter, we present the design of a simple signal Interrogator for optical fiber-based white light Fabry–Perot (F-P) interferometers. With the hardware being composed of only a flat fused silica wafer and a CCD camera, this Interrogator translates the spectral interference into a spatial interference pattern, and then demodulates the F-P cavity length with the use of a relatively simple demodulation algorithm. The concept is demonstrated experimentally in a fiber optic sensor with a sapphire wafer as the F-P cavity.

high speed solid state interferometric Interrogator and multiplexer for fiber bragg grating sensors
Journal of Lightwave Technology, 2011Co-Authors: Paweł NiewczasAbstract:We report on the design and prototyping of a robust high-speed interferometric multiplexer and Interrogator for fiber Bragg grating sensors. The scheme is based on the combination of active WDM channel switching and passive, instantaneous interferometry, allowing the resolution of virgin interferometric Interrogators to be retained at MHz multiplexing rates. In this article the system design and operation are described, and a prototype scheme is characterized for three sensors and a multiplexing rate of 4 kHz, demonstrating a noise floor of 10 ne/√Hz and no cross-sensitivity. It is proposed that the system will be applicable to demanding monitoring applications requiring high speed and high resolution measurements across the sensor array.

Simultaneous Interrogation of Multiple Fiber Bragg Grating Sensors Using an Arrayed Waveguide Grating Filter Fabricated in SOI Platform
IEEE Photonics Journal, 2015Co-Authors: Andrea Trita, Joan Vermeiren, Danae Delbeke, Pieter Dumon, Eli Voet, Shibnath Pathak, Dries Van ThourhoutAbstract:© 2009-2012 IEEE. A novel fiber Bragg grating (FBG) Interrogator is demonstrated based on an optimized arrayed waveguide grating (AWG) filter. The AWG response is optimized to achieve large crosstalk between the output channels, which allows simultaneous detection of multiple FBG peaks, using centroid signal processing techniques, without constraints on the minimum FBG peak spectral width. The measured Interrogator resolution is 2.5 pm, and the total measurement range is 50 nm. The device is fabricated in a silicon-on-insulator platform and has a footprint of only 2.2 x 1.5 mm. A novel approach to minimize the polarization dependence of the device is proposed and experimentally demonstrated.
