Photonic Crystal Fiber Sensors for Strain and Temperature Measurement
Figure 9
(a) Temperature responses of the PCF-MZI with transmission spectrum in Figure 8 (circular points) and an SMF-MZI with output spectrum shown in the inset (rectangular points). Solid lines: linear fits. (b) Strain responses of the interference peaks as functions of strain (PCF-MZI: left axis, filled circles, SMF-MZI: right axis, open squares). The solid and dash lines are the corresponding linear fits for the PCF-MZI and SMF-MZI [25].
