Abstract

In this paper, we report on nonlinearity compensation for a solid-state fiber Bragg grating (FBG) sensor interrogation system based on an arrayed waveguide grating (AWG) device. A lookup table with calibration data is used to improve system linearity. A reduction in the absolute value of the measurement error from 120 mu strain or 15 degrees C to 4.8 mu strain or 0.6 degrees C, respectively, is experimentally demonstrated.
