Latest Patents

Grabherr's notable patent is titled "Vertical extended cavity surface emission laser and method for manufacturing a light emitting component of the same." This invention addresses the process of creating a light-emitting component for a vertical extended cavity surface emission laser (VECSEL). The method involves epitaxially growing a layer stack on a semiconductor substrate. This layer stack consists of an active region, an upper distributed Bragg reflector, and a n- or p-doped current injection layer between the active region and the semiconductor substrate. An innovative step in the process is the bonding of a mechanical support or submount to the layer stack's upper side, followed by the removal of the semiconductor substrate. The patent also discusses the optional deposition of a metallization layer on the lower side of the layer stack, along with the bonding of an optically transparent substrate. This method ensures a uniform current injection and facilitates effective heat dissipation, resulting in a high-performance VECSEL.
