Project 4 : The Fundamental Mechanisms Study of IR and THz Nanostructure Lasers for National Security Application

 

           This research project aims to study the fundamental mechanism of the optoelectronics devices, focusing on the military applications. Examples include,
(1) the study of hot carriers for improving the laser and low/high energy infrared optoelectronics devices, (2) the study and design of nonlinear optics systems for long-distance bomb detection by using infrared laser and coherent anti-Stoke Raman spectroscopy that has high sensitivity. In addition, for telecommunication, the project covers the study and development of high intensity laser for quantum encrypted telecommunication with nonlinear optical process.
