Abstract
Light sources on the micro and nano-scale are of great interest in recent years. Especially for data communication over centimeters densely integrated lasers are required. Ultra-small devices have been demonstrated[1]; the efficiency of such devices on the other hand is far behind values demonstrated for larger integrated laser concepts [2]. As a consequence the density of laser integration is currently limited by power consumption and cooling properties rather than the actual device footprint. In this work we present a design and first fabrication trials for a micron-scale laser promising record efficiencies exceeding 20%. A schematic representation of the laser is shown in figure 1 a).
