Abstract

A Fiber Bragg Grating (FBG) sensor interrogation system using Arrayed Waveguide Gratings(AWGs) demultiplexer is designed and studied theoretically and experimentally. By using a temperature tunable arrayed waveguide grating (AWG), the center wavelength of the FBG sensor is successfully interrogated, with the linear temperature dependence of the AWG transmission wavelengths. Initial results show that the proposed wavelenght interrogation technology using AWG demultiplexer could potentially offers a low-cost, compact, and high-performance solution for the interrogation of FBG distributed sensors and multisensor arrays.
