| 摘要 |
The present invention relates to an injection non-coherent emitter that ensures the output of a directed, spontaneous and outflowing radiation at reduced divergence angles with increased external efficiency as well as with increased energetic and luminous power. This emitter includes, in the whole heterostructure (2), a plurality of layers and sublayers having compositions and thicknesses that lay within predetermined ranges, and also includes a plurality of layers for the radiation output area (7). This invention also relates to different modifications in the heterostructure and the output area which allow for the output of the radiation in different controlled directions, including in a direction perpendicular to the active layers of said emitters. This invention further relates to multiple-beam non-cherent emitters, including radiating rulers and matrices having autonomously controlled beams. <IMAGE> |
