Two types of terahertz sources with two-section periodical waveguide structure are studied by simulations. The operation frequency of the rear section (section-II) is the fourth harmonic of that of the front section (section-I), and section-II can operate both in the forward wave region and backward wave region. The critical factor that may affect the proper functioning of this kind of sources—overbunching—is discussed, and the corresponding solutions are proposed. These sources, with millimeter in length, can generate 1 THz wave radiation with power over 1 W, so, they are promising table-top and relatively high power terahertz sources.
