Optical properties of Gallium Phosphide (GaP) have been investigated by means of Kramers Kronig method. Optical properties such as refractive index, extinction coefficient, dielectric constant, transmittance, absorption coefficient, reflectance, reflection coefficient and optical conductivity are presented in the energy range 1.03 ?? 6.01eV. The calculated optical properties of GaP indicate promising device applications such as the design of optoelectronic devices, electronic and photonic devices.
