Description
Summary:Polarization-stable 980 nm oxide-confined vertical-cavity surface-emitting lasers with 3[mu]m 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[degrees]C from the threshold to 4mA.
