Kompletní popis

Quantum cascade lasers are unipolar semiconductor lasers based on intersubband transitions in quantum wells. They have shown laser operation from above 100 THz down to the terahertz region and are promising sources for the terahertz region (0.3-10 THz) which is lacking of efficient narrowband radiation sources. A low frequency quantum cascade laser design is developed that faces the emerging challenges when the photon energy approaches the broadening of the energy levels. A record lowest operation frequency of 1.2 THz is demonstrated. A hybrid laser-oscillator for the terahertz is developed in the second part of this work, consisting of an optical gain medium and an electronic resonator. The resonator is an inductor-capacitor resonant circuit. The so called circuit based laser has the property of being a deep sub-wavelength sized microcavity laser. The effective mode volume is among the smallest for electrically pumped lasers. The circuit based resonator in combination with an active region could lead to a class of new devices to generate and manipulate terahertz radiation that exploit cavity quantum electrodynamic effects.
