Abstract

This project analyzed the impact of coating thickness on Single-Mode Fiber (SMF) and D-Shaped Fiber Sensors. Graphene was applied as the coating material using the drop casting method. The study aimed to investigate the influence of different coating thicknesses on the transmission spectrum of these sensors and examine the relationship between coating thickness and sensitivity. Coating thicknesses ranged from 0 to 21.523 mm, measured using a 3D laser microscope. The analysis revealed that coating thickness significantly affected the optical characteristics. SMF sensors showed small changes in the transmission spectrum with increasing coating thickness. D-shaped fiber sensors, with their unique cross-sectional shape, demonstrated a redshift in the transmission spectrum. Thinner coatings had peak points around -45.055 dBm, while thicker coatings had peak points around -63.646 dBm. These findings provide insights for optimizing the coating process and customizing fiber optic sensors with graphene coatings. Future research can explore alternative methods, materials, and applications for graphene-coated fiber sensors.
