Keywords:InGaN quantum well, polarization, deformation potential

In this study, to stabilize the polarization of emission in the c-plane InGaN-QW-VCSELs, we introduced anisotropic strain in the in-plane by applying stress. Then, from polarization PL measurements, we demonstrated that optical anisotropy is induced in the c-plane QWs, and furthermore, we obtained knowledge about the deformation potential D5 of InGaN.
