Photonic Crystal Fiber Sensors for Strain and Temperature Measurement

Abstract EN

This paper discusses the applications of photonic crystal fibers (PCFs) for strain and temperature measurement.

Long-period grating sensors and in-fiber modal interferometric sensors are described and compared with their conventional single-mode counterparts.

The strain sensitivities of the air-silica PCF sensors are comparable or higher than those implemented in conventional single-mode fibers but the temperature sensitivities of the PCF sensors are much lower.
