The effect of the changes of the length of the sodium chloride in the tapered fiber region as a function of the concentration/absorption coefficient on the absorbance response are observed. Results showed the linear relationship of the absorbance with the length of the sensing solution as well as with the absorption coefficient. The sensitivity of the system is calculated to be less than 0.0058 a.U/mm. The findings exhibited the potential of the Monte Carlo simulation as a platform for a preliminary study of tapered fiber sensor applications. � 2020 IEEE.en-USAbsorption-based sensorMonte Carlo simulationTapered fiber sensorConference Paper9394
