<p>This study investigates the effects of frequency chirp and nonlinear effects on soliton pulses. By varying the beginning frequency chirp of the input soliton, one can compute the usable conversion. A chirp pulse amplification was developed. This enhances the chirp value and affects a different order of solitons, causing the soliton to split and develop several new essential solitons. There is a significant contribution of nonlinearity to the intensity of the impulses from beginning to end. It is also demonstrated that high-order soliton pulses are better compressed and broken up when there is a positive chirp, whereas the opposite is true when there is a negative chirp. As one increases the soliton order, these effects become more noticeable. A photon crystal fiber was created utilizing the splite-step Fourier method (SSFM), which was proposed and verified using the MATLAB program. The importance of studying soliton effects in solid-core optical crystal fibers lies in controlling dispersion and nonlinearity to generate stable pulses, which is essential for the development of optical communications and metrology techniques.</p>
