摘要	Given the high symmetry of vertical-cavity surface-emitting lasers (VCSELs) along their emission axis, these lasers demonstrate intrinsic polarization instability. In this study, we report the anisotropy oxide apertures of VCSEL formed by the unsymmetrical airflow distribution during the wet oxidation process. The polarization directions of VCSELs with anisotropy oxide apertures are well-controlled. VCSELs with oxide apertures of 2 m 4.6 m achieve an orthogonal polarization suppression ratio of more than 20 dB and side-mode suppression ratio of more than 25 dB. In addition, an asymmetric far field distribution is observed, which can be ascribed to the asymmetric oxide apertures. 2021
