Polarisationskontrollerade VCSELer som använder sig av en strömbegränsande apertur |
摘要 |
A vertical cavity surface emitting laser (VCSEL) having asymmetrical optical confinement is described. Polarization of VCSELs having symmetrical structures tend to be unpredictable and switchable. The VCSEL of the present invention has vertically etched apertures into the top bragg mirror in order to confine the optical path into an asymmetric structure. This has the effect of locking polarization into a fixed mode. |
