| Abstract: | Application of photonic crystal fibers (PCFs) leads to extensive improvement in the performance of traditional fiber sensors. Fiber sensors based on PCFs exhibit higher accuracy and temperature characteristics towards sensing strain as well as the refractive index of liquids, and are capable of incorporating different types of coupling structure units that comprise interferometer. Basic structures,operating principles and recent research progresses of photonic crystal fibers sensor based on Bragg grating, long-period grating (LPG) and interferometer are reviewed. |
