Terahertz technology : fundamentals and applications Terahertz Technology presents information about Terahertz science Terahertz photodetectors and Terahertz Lasers. A special emphasis is given to room temperature operation of long wavelength photodetectors based on novel quantum dots (Centered Defect Spherical Quantum Dots). Moreover a complete analysis of systems based on Quantum Cascade structures to detect far infrared wavelengths is provided. Finally the book presents Terahertz laser principles considering multi color lasers in this range of wavelengths. Back cover
