10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM2010). 2nd International Workshop on Thz Radiation: Basic Research and Applications (TERA 2010)
We report of a easy-to-use terahertz radiation source, which combines a QCL operating at 3.1 THz with a compact, low-input-power Stirling cooler. The QCL, which is based on a two-miniband design, has been developed for high output powers and low electrical pump power. The whole system weighs less than 15 kg including cooler, power supplies etc. The peak output power is 8 mW at 3.1 THz. The applicability...
The application of the microwave approach to the developing of the terahertz (THz) frequency range allowed producing the set of precise methods and devices for various applications. The midpoint of the development was the using of the mixers and multipliers on the quantum semiconductor superlattices which allow more effective signal transformation in comparison with usually used devices based on Schottky...
Terahertz anomalous dispersion and material physical properties leads to form the region with negative dielectric permittivity (DP) that is created around the polar frequency oscillations in three crystalline modifications of boron nitride will be analyzed in our report. Our analysis based on the simple quantitative criterion of existence the negative DP bands. Seven vibrations in different crystalline...
