Abstract

In this paper, we present results regarding the influence of structural parameters of a photonic crystal fiber on its loss through theoretical and simulated studies. We utilized a photonic crystal fiber based on fused silica glass, with its central air hole infiltrated with tetrachloroethylene (C2Cl4). The results indicate that the loss is significantly dependent on the lattice pitch and the diameter of the air holes in the cladding region. As the diameter of the air holes increased or the lattice pitch decreased, the loss also increased. This finding holds significant importance in the design of photonic crystal fiber structures. By optimizing structural parameters such as lattice pitch or hole diameter, we can design and fabricate photonic crystal fiber structures with low loss, which is crucial for applications in optical communication.
