10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM2010). 2nd International Workshop on Thz Radiation: Basic Research and Applications (TERA 2010)
In this work, new approach to gain spectra tuning have been developed for quantum-cascade structures. The spectral tuning is based on the phase space filling effect evoked by optical driving signals inducing interband electron transitions and populating of conduction lasing subbands. For three-well THz GaAs/AlGaAs quantum-cascade structure, mathematical modeling show that gain spectra can be shifted...
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...
