A gallium phosphide (GaP) based photonic crystal fiber (PCF) with hexagonal air hole arrangements is introduced in this study that reveals high birefringence (Br) and nonlinear coefficient (NLC). Numerous optical properties, such as birefringence, nonlinearity, dispersion, confinement loss, effective area, core power fraction, etc. are studied by finetuning the geometrical variables, applying finite element method (FEM). The numerical analyses demonstrate an ultra-high Br of 59.1 × 10−2 NLC 2.37 105 𝑊−1𝐾𝑚−1 a large negative dispersion ―3875.21 ps. nm―1 . km−1 can be accomplished at wavelength 1.55 𝜇𝑚. Consequently, developed PCF applied plethora intriguing applications, including supercontinuum generation, telecommunications,
