Parametric optimization of hollow core photonic crystal fiber and its comparison with conventional single mode fiber

Photonic Crystal Fibers (PCF) are flexible in its structural dimensions such as core radius, cladding hole radii and pitch. This flexibility permits the researcher to optimize the fiber to its best performance for desirable applications. Therefore, the objective of this paper is to propose an optimized Hollow Core Photonic Crystal Fiber (HCPCF) by investigating the optical parameters of the fiber. In addition to this, the manuscript intends to provide a brief comparative analysis of conventional Single Mode Fiber (SMF) and proposed HCPCF. Major parameters for study are taken as confinement factor, confinement loss, dispersion and birefringence. Based on these optical parameters, efficiency of the design is judged, where all the structural entities are chosen and investigated sequentially. The optimized value for pitch, radius of air-holes of core and cladding region of HCPCF are calculated as 3.8 µm, 18.01 µm and 1.2 µm, respectively. On comparison of HCPCF and conventional SMF, it is observed that the CF for the proposed HCPCF is higher than conventional SMF. On the other hand, confinement loss is lower for the conventional SMF. Thus, it is inferred that this optimized HCPCF can be used for high power small distance communication or sensing based optical applications.
