N2 - An uncomplicated photonic crystal fibre design based on an octagonal core hole and hollow circular cladding holes in two layers has been introduced to detect food additives. The numerical analysis of the design is executed through simulation performed in COMSOL Multiphysics software with the infiltrated test analytes: saccharin, sorbitol, and butyl acetate, operating from 1.6 to 4.0 μm wavelength variation. The performance of the presented sensor is established by evaluating the principal performance parameters: effective refractive index, power fraction, relative sensitivity, and confinement loss. At an operating wavelength of 2.0 μm, the sensor design depicts best relative sensitivities of 98.06% for saccharin, 97.05% for sorbitol, 95.81% for butyl acetate, and 3.82 × 10-23 dB/m for saccharin, 3.44 × 10-22 dB/m for sorbitol, and 1.81 × 10-21 dB/m for butyl acetate for confinement loss, which is extremely low. Hence, the proposed food additive sensor is suitable for actual sensing applications based on these obtained results.
