A comparative analysis of basic and enhanced hole structures in photonic crystal fibers

This study introduces a novel photonic crystal fiber designed with several zero-dispersion wavelengths with exceptional characteristics for dispersion compensation in telecommunication applications. Two distinct photonic crystal fibers were designed and compared: one with periodic arrangement of air holes, the other with 12 extra air holes. The performance metrics of the fibers were analyzed, revealing a notable advantage for the designed fiber with supplementary air holes. Moreover, the dispersion curve analysis provides an intriguing insight into the behavior of zero-dispersion wavelengths (ZDWs), showcasing the PCF with extra air holes as a potentially rich source of multiple ZDWs. This innovative PCF design holds the potential to advance dispersion compensation capabilities, enhancing the efficiency and quality of optical signal transmission in telecommunication systems.
