Abstract
This paper highlights the losses arising from bending that plays a vital role in long-term communication purposes. To get better transmission it is very essential to control the losses. Losses arising from bending of photonic crystal fiber (PCF) can also be controlled by altering the structural parameter (d/? and ?) that regulates the photonic crystal fiber structure. Different materials (viz. crown and phosphate) based PCF with lower bending losses has been reported by exploring the whole communication band (0.2-2µm) with variable structural parameters and bending radii. During bending of a fiber, evanescent field energy drives light towards cladding and a subsequent attenuation in the guidance of light energy occurs, which generates losses and can be controlled by altering the structural parameters in the PCF. Therefore, failure in total internal reflection is the major contribution towards these losses. In this study, a very low bending loss ~ 0.11 dB/km and ~0.08 dB/km have been observed for crown and phosphate based PCF. Also, an interesting phenomenon has been observed during the study that with increase in ? for constant d/?, losses are found to increase up to the λ ~1.2µm and then started decreasing with increase in ? which can be useful for the experimentalist during fabrication. Although this work can provide a valuable approach to the engineers to develop a newer kind of PCF model that can lower losses with respective change in material domain.
