Inspection of an HSH-PCF for optical Communication with high Non-linearity, birefringence and negative dispersion

This research paper proposes a simple hexa-spiral hexagonal photonic crystal fiber (HSH-PCF) design containing circular timbered air holes, exhibiting a highly nonlinear coefficient and negative dispersion with lower confinement loss. The Finite Element Method (FEM) has been applied here to inspect guiding properties. This propounded HSH-PCF covers all optical bands and windows in the design. The simulation analysis proves that the proposed HSH-PCF achieves a high nonlinear coefficient of 113.8(W.km)-1 at the wavelength of 1.55μm, negligible confinement loss, and the maximum negative dispersion amplitude of -864.5ps.(nm.km)-1. At a 40kW peak power with 20fs input pulse through the 1.5cm of fiber length, the PCF represents a wide-band supercontinuum generation band spectrum. So, the HSH-PCF officiates in several applications like high bit-rate data transfer, amplification of optical parameters, sensor designing of optical fibers, maintaining polarization, dispersion-compensating fibers, spectroscopy system, and other various purposes.
