We present a model for a broadband terahertz (THz) system that employs electro-optic (EO) polymer films for THz generation via optical rectification and THz detection using EO sampling. In this model, we take the laser spectral bandwidth, pulse distortion, and the material properties of the EO medium into consideration, at both the generation and detection sites, and investigate the roles they play in affecting the performance of the THz system. This model provides us with a guide to select suitable EO materials and proper light sources for bright, broadband THz systems.
