Extending the spectral range of THz quantum cascade lasers
Recently, substantial progress has been made on the temperature performance of Terahertz Quantum Cascade Lasers (THz QCLs) around frequencies of 4 THz. The project shall study whether similar results can be obtained in a wider spectral range. For this purpose, detailed simulations were performed based on the nonequilibrium Green’s function model developed earlier in the group. The main issue is to
