Abstract
We report the electrically pumped emission of midinfrared (MIR) radiation from bipolar quantum-dot lasers during near-infrared lasing. The MIR spectrum exhibits a peak at 16 μm and is dominantly TM polarized. The MIR intensity exhibits a superlinear dependence on the injection; a maximum MIR power of 0.1 μW per facet was realized. Such a device is also modeled theoretically, and conditions for MIR lasing are predicted.Keywords
