Polarization-stable 980nm oxide-confined vertical-cavity surface-emitting lasers with 3 μm diamond-shaped aperture are fabricated by comprehensively utilizing the anisotropic properties of wet etching and wet nitrogen oxidation of III-V semiconductor materials. Polarization-stable operation along the major axis of the diamond-shaped oxide aperture with 11 dB orthogonal polarization suppression ratio is achieved in a temperature range of 15-55°C from the threshold to 4 mA.
