Publishing a Scientific Paper

Lecturer Dr. Safaa Muhammad Ridha from the Physics Department at the College of Education for Pure Sciences published a scientific paper titled “Fano-type resonance structures based on a combination of fiber Bragg grating with a Fabry-Perot interferometer.” The paper was published in the International Journal of Modern Sciences, classified as Q1. The research aims to open new horizons for utilizing the asymmetric resonance effect of composite structures in sensing applications, on the one hand, and also to discover a numerical mathematical model for fiber optic sensors integrated into Fano resonant structures based on a combination of a fiber Bragg grating and a Fabry-Perot interferometer. The research also includes a study of Fano resonant structures based on a combination of a fiber Bragg grating and a Fabry-Perot interferometer. The presented mathematical model can be used as a digital twin of the integrated fiber optic sensor. Using the presented mathematical model and experimental data, we can find a simple non-metric Fano resonance in the optical fibers resulting from the superposition of two wave resonance processes. Similarity between the simulated and real integrated sensor spectra was demonstrated. The study identified all the necessary parameters for any implementation of a sensor dedicated to each specific task. The optical fiber structure is used as a gas concentration sensor, and its sensitivity is determined by the dependence of the refractive index (transmittance) and permeability of the polymer material on the environmental gas concentration, temperature, and humidity. Furthermore, the specific polymer must be selected based on the type of gas under test.
