Optimization of microstructred fiber’s mode distribution for high speed data transmission

Photonic crystal fibers (PCFs) have drawn significant attention in recent years due to their unique properties and potential applications in various fields. In this paper, investigations are done on the mode distribution and structural parameter optimization of a PCF for both wavelength division multiplexing (WDM) and insulator applications. Finite difference time domain method is used for field distribution. Extensive MATLAB simulations are performed to analyze the mode distribution of the PCF. Simulated results show that the mode distribution is highly dependent on the structural parameters of the fiber, such as the photonic crystal lattice period, element radius, refractive index of the background material and photonic crystal elements. Furthermore, the effect of the structural parameters on the dispersion and attenuation of the PCF is also investigated. It has been demonstrated that the structural parameters of PCFs can be adjusted to achieve low dispersion and attenuation so that the PCF can be suitable for WDM and insulator applications. The simulation results are presented to validate the claims and various applications and use cases of the proposed structure are also discussed.
