Design and Simulation of C-Shaped Optical Fiber Sensor

This paper presents a C-shaped optical fiber sensor for refractive index measurement. The design and simulation of the C-shaped optical fiber were conducted via Wave Optics Module-COMSOL Multiphysics®. The refractive index measurement ranging from 1.30-1.40 is performed. The simulation results showed that the C-shaped design has the potential to act as a refractive index sensor with sensitivity of up to 0.966348101, higher than simulated D-shaped OFS with estimated sensitivity of up to 0.966334412.
