This study introduces an innovative examination of the stochastic Kaup{Newell equation within the realm of ¯ber Bragg grating, signifying a pioneering e®ort in this area. The study uses two main methods for integration: the ðG0 G Þ-expansion method and the enhanced direct algebraic method to ¯nd di®erent one-step solutions to the Kaup{Newell equation. The outcomes of this research are multifaceted, revealing an array of optical soliton solutions such as dark, singular, bell-shaped, kink-shaped, bright, and straddled solitons. These ¯ndings contribute a novel perspective on the behavior of optical solitons in ¯ber Bragg gratings, which are essential for optical communications and signal processing.
