Keyword Polarization arbitrary manipulated terahertz sources can promote many disruptive technologies and enable enormous applications but face a severe shortage. In article number 2000099 , Xiaojun Wu, Tianxiao Nie, and co‐workers demonstrate a highly efficient generation and arbitrary manipulation of chiral terahertz waves in topological insulator (Bi 2 Te 3 )‐iron (Fe) heterostructures through delicately engineering linear photogalvanic effect and spin‐to‐charge conversion effect induced by femtosecond laser pulses for the first time.
