The refractive index and dispersion of the sensors are dependent on the parameters of the photonic crystal fibers

Abstract

Mohammed Salim Jasim

A refractive index sensor based on photonic crystal fibers (PCFs) using finite element method (FEM) has been suggested in this paper. The designed fiber has a hexagonal cladding structure running around its solid core, with six air holes rings. Using the FEM, effective refractive index, confinement loss, fundamental mode laser profile, and sensor resolution are investigated. This constructed sensor characterized by low confinement loss and high resolution such that a small change in the analyte refractive index could be detected which could be useful in detecting changes in biological molecule reaction information as well as in medical applications in areas such as toxins, medication residues, vitamins, antibodies, proteins and parasites.
