Abstract
For polarization-sensitive applications such as magneto-optic disks and coherent detection systems, the polarization state of surface emitting (SE) lasers must be well defined. From the measured polarization characteristics, it was found that the output of mesa-structure SE lasers were linearly polarized1,2 and homogeneous lasers were unstable in terms of polarization state3. Several polarization control methods were also suggested2. However, the stress would affect the polarization state of SE lasers and it is necessary to clarify its effect for stable polarization control.
