Engineering the Next Generation of Terahertz Laser Imaging Systems (2016–2019)
This project will engineer a disruptive technology based on the terahertz quantum cascade laser for applications in biomedical imaging. Our approach, using the semiconductor laser in the optical-feedback interferometer configuration, will afford significant advantages over conventional terahertz imaging platforms. The project will explore new semiconductor physics of a quantum cascade laser under optical-feedback, engineer the semiconductor laser based platform for medical diagnostic applications, and develop supporting numerical techniques. This innovation will introduce the first terahertz imaging system based on optical-feedback in a semiconductor laser suitable for early skin cancer detection.
