| dc.description.abstract | The technology and performance of quantum cascade lasers has rapidly developed since it was firstly unveiled in 1994. This type of laser has a feasible design, micro meter size and potential for emission of long wavelength (mid-infrared to far-infrared); hence, it can be useful for multiple applications. Because of the lack of light source in the mid-infrared range (wavelengths of 3-30 μm), the mid-infrared quantum cascade lasers with high quality radiation are playing important roles in several research fields such as chemical and bio-chemical spectroscopy, free space gas sensing and communication. This work reports the design, fabrication and characterization of the mid-infrared quantum cascade lasers. The theoretical part of this thesis presents the simulation methods of the mid-infrared quantum cascade lasers. The modeling results include the Schrödinger equation solver, quantum transition simulation, and the optical property calculation, among others. The experimental part reports the whole process of the mid-infrared quantum cascade lasers completed at the University of Waterloo. In summary, the design, optimization, fabrication and characterization of the mid-infrared quantum cascade lasers is verified and improved. | en |
