Reflectance, photoreflectance and photoluminescence spectra of GaN substrate prepared by lateral epitaxial overgrowth technique were measured at low temperature. All spectra were discussed based on model exciton-polariton picture, and the spectra were successfully explained by the model. Temperature dependence of transition energies was well described using a model that assume Einstein phonons.
