Polymer-based surface relief Fiber Bragg grating sensor for strain and temperature sensing (Conference Presentation)

We present a new sensor design of a polymer-based Fiber Bragg Grating (FBG) on a D-shaped optical fiber for detection of variation of temperature and strain. The gratings are molded and are at the proximity to the fiber core, which is made by fiber-assisted UV lithography. The process is suitable for generating optical fiber-based sensors with high repeatability in simple processes. The proposed sensor can be multiplexed, so an array of the proposed sensors will be suitable in detecting a wide range of environmental conditions.
