| 中文摘要 | we investigate the uniaxial strain effect in the c-plane on optical properties of wurtzite gan based on k center dot p theory, the spin-orbit interactions are also taken into account. the energy dispersions show that the uniaxial strain in the c-plane gives an anisotropic energy splitting in the k(x) - k(y) plane, which can reduce the density of states. the uniaxial strain also results in giant in-plane optical polarization anisotropy, hence causes the threshold carrier density reduced. we clarify the relations between the uniaxial strain and the optical polarization properties. as a result, it is suggested that the compressive uniaxial strain perpendicular to the laser cavity direction in the c-plane is one of the preferable approaches for the effcient improvement of gan-based laser performance. |
