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.
It is shown that one can control the spectrum of electromagnetic wave propagating through dielectric medium by applied external electric field. The control of field spectrum may be used for designing of the controllable filters in the terahertz and optical band for uninterrupted and pulse signals.
Nonlinear dynamics of free-carriers in direct bandgap semiconductors at terahertz (THz) frequencies is studied using high power, few-cycle pulses. Techniques as Z-scan and THz-pump/THz-probe are employed to explore nonlinear interactions in both n-doped and photoexcited systems. The physical mechanism that gives rise to such interactions will be discussed in details.
