Application of acousto-optical materials for modulation of sub-terahertz signal in coplanar structures

This paper discusses construction issues of the experimental setup for verification of possibilities of acoustooptic materials application in sub-terahertz signal modulation. First, the concept of the modulating device is outlined. Then, the requirements and candidate substrate materials for such apparatus are considered as well as design constraints concerning construction of high frequency transmission line and electroacoustic transducers. Finally, the design of the experimental subterahertz modulator and results of the electromagnetic simulations of its constituents are shown.
