Optical anisotropy in the growth plane has been observed by reflectance and photoluminescence (PL) spectroscopy on nitride epilayers grown on A-plane sapphire. This anisotropy results from the strongly anisotropic thermal strain which is such that the wurtzite symmetry goes from C 6v to C 2v . Time-
