Abstract EN
Photonic crystal fiber interferometers (PCFIs) are widely used for sensing applications.
This work presented solid core-PCFs based on Mach-Zehnder modal interferometer for sensing refractive index.
The general structure of sensor was applied by splicing short lengths of PCF in both sides with conventional single mode fiber (SMF-28).To apply modal interferometer theory collapsing technique based on fusion splicing used to excite higher order modes (LP01 and LP11).
A high sensitive optical spectrum analyzer (OSA) was used to monitor and record the transmitted wavelength.
This work studied a Mach-Zahnder interferometer refractive index sensor based on splicing point tapered SMF-PCF-SMF.
Relation between refractive index sensitivity and taper waist diameter were studied through simulation and experiments.
The experimental and simulation results show that sensitivity would be increased with a decrease of taper waist diameter.
The response of the PCFI is observed for a range of refractive index values from (1.33 to 1.38).
When the length of PCF was (4)cm with different taper waist diameter (125,107,90,60)μm, the maximum refractive index sensitivity of (20 pm / RIU) was achieved.
When taper waist diameter became (60)μm, the rate of increase in sensitivity was 12.4% compared with the taper waist diameter (125)μm.
