Quantum well structure

<p><strong>Background</strong><br>

Quantum-well inter-subband devices, such as quantum-well infrared photo-detectors (QWIPs) and quantum cascade lasers (QCLs) are ideal for a variety of ground and space-based applications. Night vision, early warning systems, navigation, flight control systems, weather monitoring, security and surveillance are among the different applications based on QWIPs. QCLs are ideal candidates for the remote sensing of gases in the atmosphere.</p> <p style=”margin-bottom: 0.0001pt;” class=”MsoNormal”><strong>Technology</strong><br> The invention is a quantum well structure including a quantum well layer arranged between two barrier layers. The invention further refers to quantum well photodetectors and quantum cascade laser. <br> <strong><br> </strong></p> <p style=”margin-bottom: 0.0001pt;” class=”MsoNormal”><strong>IP Rights</strong><br> German Patent DE 103 35 443 B4<br> US Patent US 7,893,425 B2<br> European Patent Application<br> <br> <strong>Patent Owner</strong><br> Humboldt-Universität zu Berlin, Germany</p> <p> </p>
