1.  Dr. Christian Pflügl, EOS Photonics, USA
Invited Talk: Monolithic Quantum Cascade Laser Arrays for Spectroscopy and High Power Applications
Speaker Biography: Dr. Pflügl is a co-founder and current Vice President of Research and Development at Eos Photonics. Dr. Pflügl received his Ph.D. in Electrical Engineering in 2005 from the Vienna University of Technology, Austria and his M.S. in Applied Physics from the University of Regensburg, Germany in 2002. From 2006 to 2010, he worked as a Research Associate at Harvard University in the group of Prof. Federico Capasso. Dr. Pflügl has authored or coauthored more than 50 technical papers and more than 90 conference proceeding papers/presentations. He has also authored or co-authored numerous granted and provisional patents.

Summary: Since their invention in 1994, mid-infrared Quantum Cascade Lasers (QCLs) have attracted increasing interest for several applications, such as infrared countermeasures and chemical sensing. Recent breakthrough results achieved during the DARPA EMIL (Efficient Mid-Wave Infrared Lasers) program have strongly contributed to this development. Single devices operated in continuous wave at room temperature have reached multi-Watt output power with efficiencies exceeding 20%, making them attractive for high power applications such as infrared countermeasures. For spectroscopy, distributed feedback (DFB) QCL technology has been successfully commercialized and those devices are employed for a variety of applications including greenhouse gas detection, industrial process control, and explosives detection. While the use of single devices has demonstrated the potential of QCLs for the above mentioned applications, next generation devices with higher power and increased spectral coverage are sought to increase the application space for QCL technology.
