Abstract Abstract In the process of fnding suitable solid-state sources, emitting acceptable power levels at THz frequencies, a circuit simulation model is presented, that is capable of reproducing measurement results of state-of-the-art photomixers. Reading this thesis requires a basic knowledge in physics of semiconductors and in using the Advanced Design System simulator from Agilent Technologies. The structure of the thesis is as follows: Chapter 1 gives an introduction to the concept of photomixing. The state-of-the-art photomixers, based on this technique, are presented in the following. Chapter 2 describes the physical modeling of the PIN photodiode and its extensions, capable to be implemented in an existing circuit simulator. Chapter 3 contains the modeling of the traveling-wave structure, in which the pro- posed PIN phototiode can be implemented. Chapter 4 gives an instruction to the implementation of the proposed models into the above mentioned circuit simulator. Chapter 5 shows the achieved simulated performance of each device and compares them with results obtained from measurements.
