Abstract
In this work, we design, simulate and compare the performance of two in-line MZI concentration sensors; in one sensor, Thinned Fibre (TF) is sandwiched between two conventional Single Mode Fibres (SMFs) and in other Photonic Crystal Fibre (PCF) is sandwiched between two Single Mode Fibres (SMFs). Change in concentration which results in change in refractive index change is measured using both the sensors. Sensitivity of the sensor using PCF is found better as compared to that using TF.
