| Basic problems of acousto-optic interaction in terahertz region of electromagnetic spectrum are considered. We obtained experimental results that are fitted by generalized theoretical model developed with the goals to describe the interaction in detail. Our analysis showed that crystalline germanium is one of the best materials to observe the acousto-optic interaction in the terahertz range. The carried out study proved that a germanium based acousto-optic device could be used for fast and reliable deflection of monochromatic radiation in the terahertz spectral region. |
