Treść
In this paper we present selected modifications of vertical-cavity surface-emitting lasers, aimed at their further miniaturization, as well as at improvement of their efficiency and reliability. The key issue is to eliminate semiconductor Bragg mirrors from the laser structure. These multi-layer components not only significantly increase complexity of the laser chip, but also limit heat flow within the structure, hindering effective cooling of the active region and thereby decreasing efficiency of lasing. In the discussed here, alternative constructions of surface emitting lasers the Bragg mirrors have been replaced by other optical elements of similar properties. In the first case an internal cavity of the laser is enclosed by high-contrast subwavelength gratings, in the second one - by heat-spreading diamond plates. The proposed innovations have been validated by numerical calculations and confirmed experimentally. All presented results were obtained as a part of research on vertical-cavity surface-emitting lasers, conducted jointly by Institute of Electron Technology and Institute of Physics of Technical University of Lodz.
