Abstract

We report on the generation of a terahertz (THz) beam with a quasi-TEM01 mode by exploiting the interferometric recombination of two linearly polarized emitters in a combined spintronic source. A single-cycle longitudinally polarized field component is realized by tightly focusing the quasi-TEM01 beam and the scaling of the electric field strength is explored.
