Terahertz Quantum Cascade Lasers
<p><strong>Background</strong><br>
Quantum Cascade Lasers (QCLs) are currently the best electrically-pumped sources of Terahertz (THz) radiation regarding output power, linewidth, operating temperatures and efficiency. THz QCLs offer a wide field of applications ranging from astrophysics and security screening to ultrafast spectroscopy in chemistry or biology. For all these applications THz QCLs which can operate at moderate temperature are desired.<br><br> <p><strong>Technology</strong><br> The invention is a THz Quantum Cascade Laser with improved temperature performance. The THz QCL uses a strain-compensated (Al, Ga, In)As material grown on InP substrates.<br> <br> <strong> Benefits</strong><br> <ul> <li>Operating frequencies: 0.8 THz – 5 THz</li> <li>Operating temperature: 240K minimum </li> <li>Use of thermoelectric coolers</li> <li>Improved laser gain compared to common THz QCLs</li> </ul><br> <br> <strong> IP Rights</strong><br> US patent application (02/2009)<br> <br> <strong>Patent Owner</strong><br> Humboldt-Universität zu Berlin, Germany<br> University of Texas, USA</p>
