Abstract

A review is given of the present status of Si/SiGe quantum cascade emitters operating in the terahertz part of the frequency spectrum and the issues regarding making a quantum cascade laser using such technology. Potential applications will be discussed before the major issues in obtaining a laser are reviewed. Waveguides properties will be clarified before cascade heterostructure regions with sufficient gain to overcome waveguide losses are discussed. Finally the future outlook and potential for lasing will be debated.
