摘要	980-nm large-aperture top-emitting vertical-cavity surface-emitting lasers (VCSELs) were investigated through introducing the rectangular post. Both H-polarization (horizontal) and V-polarization (vertical) coexisted in the rectangular-shaped large-aperture VCSELs. Under the entire range of operation current, H-polarization dominated over V-polarization which was parallel to the shorter side of the rectangular output aperture. It was found that spectrum blue-shift of H-polarization light occurred with respect to V-polarization light at three different aspect ratios, and this can be explained by the dependence of longitudinal propagation constant on the aspect length. The rectangular post structure was found to be effective for polarization stabilization in broad-area VCSELs without serious degradation of light output characteristics.
