This paper will cover the Fourier representation for optical soliton propagation in photonic crystal fibers (PCFs), the concept of the soliton spectrum, and the technique for conducting soliton propagation in this type of fiber using the Fourier transform. By performing discrete Fourier transforms, which are utilized in the numerical evaluation of Fourier transforms, the study will determine the intensity of the pulse that takes place with a super soliton pulse and the dependability of the soliton amplitude along the photonic crystal fiber.
