This work focuses on the construction of a mathematical model for the simulation of simultaneous ultraviolet and temperature monitoring. The model was constructed based on the parameters of a typical structure that is composed of a photonic crystal fiber (PCF) filled with fluorescein dissolved in water and spliced between two conventional multimode fibers. This work is based on an investigation published in Optical Fiber Technology (2016). The mathematical model has been tested and verified to obtain a good match with previous results using the extra val function. In this work, the pH factor, temperature, and excitation power were simulated to estimate the output emission spectrum and corresponding wavelength. The simulation process enabled by the mathematical model will provide theoretical measurements that can be used in sensing applications as a theoretical PCF sensor.
