This report results from a contract tasking CNRS-University of Paris-Sud as follows The contractor shall measure resonator infrared IR modes using Fourier Transform Infrared Spectrometer FTIR and fabricate multiple quantum wells using PL to check for intersubband transitions. Initial studies will be aimed at demonstrating intersubband luminescence at terahertz THz frequencies in the valence band of SiGeC quantum structures. The next step will be to add multilayer active regions and carrier injectors for studying electroluminescence devices. In parallel, the cylindrical resonator issue will be addressed. Finally, the contractor will investigate the feasibility of cylindrical resonator electroluminescent and lasing devices.
