This comprehensive overview delves into the revolutionary advancements in mid-infrared and terahertz photonics, focusing on state-of-the-art quantum cascade lasers (QCLs). Combining real-world examples with expert guidance, it offers a thorough treatment of practical applications, including high-power continuous-wave QCLs, frequency-comb devices, quantum-electronic transport and thermal transport modeling, and beam shaping in QCLs. With a special emphasis on recent developments, such as frequency noise and frequency stabilization of QCLs, grating-outcoupled surface-emitting mid-infrared QCLs, coherent-power scaling of mid-IR and THz QCLs, metasurface-based surface-emitting THz QCLs, self-mixing in QCLs, and THz QCL sources based on difference-frequency generation, the text also provides detailed theoretical explanations of methods for efficiency maximization, design criteria for high-power continuous-wave operation of QCLs, and QCL thermal modeling. By empowering academics, researchers, and practitioners in electrical, optoelectronic, and photonic engineering, this invaluable resource paves the way for new applications and further breakthroughs in this field.
