1.  Dr. Virginie Trinite, Alcatel-Thales III-V Lab, FRANCE
Late-Breaking Results: High Power Quantum Cascade Laser Arrays
Speaker Biography: Trinite Virginie: is born in France in 1979. She graduated from the Ecole Centrale de Paris, Paris, France in 2003 and received her PhD. Degree in physics from the Ecole Doctorale of Ecole Polytechnique, Palaiseau, France in 2006. She now works as researcher at Thales Research & Technology, Palaiseau, France since 2007. Her PhD focuses on the theoretical modeling of titanium phases by ab initio calculations. Her current research focuses on theoretical modeling of semiconductor hetero-structures for QWIP and Quantum Cascade Laser devices, and more specifically on electronic transport properties.

Summary: One of the crucial points to have a high power quantum cascade laser (QCL) is to manage correctly the thermal effects. There are two ways of improving the efficiency of the laser: design a better active zone less sensitive to the elevation of the temperature as it as be done in or decrease the thermal resistance. We will introduce a new way to improve thermal dissipation by using μ-stripes array technology. These buried arrays are very appealing because they offer both lateral dissipation enhancement and beam quality control in large active region lasers.
