Characterization of the first generation CW THz emitters

Building on the findings of D12 and continuing that work this report will give a detailed account of the characterization of continuouswave operation of the first generation of sTHz emitters by ultrafast photomixing of two detuned IR lasers The output performances will be investigated as a function of operation mode excitation power material system growth conditions etc CW emission beyond 2 THz is targeted with power levels that can be a stepping stone towards the levels needed for communication purposes at carrier frequencies beyond 24 THz
