Abstract :
Summary form only given. We report the room temperature operation of a novel unipolar self-organized quantum dot FIR laser (13.3 μm) based on transitions between discrete bound electron states in self-organized dots. A typical photoluminescence spectrum of InGaAs-GaAs self-organized quantum dots is shown
