We discuss practical benefits of the nonlinear active quantum-cascade structures that support both laser action and, at the same time, nonlinear self-conversion of laser light into coherent radiation at different frequencies. We show that the proposed approach can greatly enhance the performance of quantum cascade lasers and provide new functionalities. Examples considered include extreme frequency up- or down-conversion, fast and wide-range electric tuning, and multifrequency generation.
