The book explores the development of quantum cascade lasers, focusing on their operation from above 100 THz to the terahertz region, which lacks efficient narrowband sources. It details a low frequency design achieving a record operation frequency of 1.2 THz and introduces a hybrid laser-oscillator combining an optical gain medium with an electronic resonator. This innovative circuit-based laser features a deep sub-wavelength microcavity, enabling new devices for generating and manipulating terahertz radiation through cavity quantum electrodynamic effects.
