10th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM2010). 2nd International Workshop on Thz Radiation: Basic Research and Applications (TERA 2010)
THz spectroscopy was used to investigate bovine serum albumin (BSA) flexibility in conditions ranging from lyophilised BSA to dilute 10% w/w BSA solution and highly concentrated 50% w/w BSA solutions. The simulated THz spectra of dry and hydrated BSA are in good agreement with the experiments.
Terahertz-range intracenter silicon lasers have demonstrated significant progress over past decade in expanding the frequency operation range, in manipulation of a silicon matrix as well as in lowering of optical pump threshold. While terahertz gain realized in silicon lasers has been already defined, optical losses in the active media have not been yet measured experimentally. We applied continuous...
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...
