Anisotropic apertures for polarization-stable laterally oxidized vertical-cavity lasers

Anisotropic apertures for polarization-stable laterally oxidized vertical-cavity lasers

We disclose a method of eliminating the polarization instability in laterally oxidized vertical-cavity surface-emitting lasers. By employing an appropriately shaped device aperture, we are able to make the lasers operate in a single polarization direction through their entire L–I curve.
