In order to better understand the second-order nonlinear mixing process required for the THz frequency comb generation, we present an extensive analysis of such THz DFG-QCL comb devices using a full-wave Maxwell-Bloch equation solver.

Compared to the conventional LED, more than 48.47% enhancement in the efficiency of the LED with prestrain layer can be observed which is attributed to the reduction of polarization field within MQW regions.
