The effects of spontaneous polarization on the optical properties of strained InGaN/GaN quantum wells (QW) were investigated. The reduced radiative recombination efficiency and large spectral red shifting were studied on the high excitation luminescence spectra of these quantum wells. It was shown that the additive effects of the spontaneous polarization and piezoelectric polarization induced electric field at these interface leads to substantial decrease in the interband optical transition energy and emission intensity in these QWs.
