Title: Interrogation approach of fiber Bragg gratings using arrayed waveguide grating based on photonic integrated circuit for sensing applications

Abstract: The presentation is devoted to analytical and experimental investigations of a fiber Bragg grating interrogator based on an arrayed waveguide grating fabricated using a photonic integrated circuit technology. In the speech, interrogation techniques of fiber Bragg grating sensors will be compared. The developed algorithm for detecting the reflection spectrum maximum of fiber Bragg gratings will be demonstrated. Moreover, experimental measurements of temperature and mechanical stress using the proposed interrogation technique will be described. In addition, the promising sensing applications of the interrogator will be outlined
