abstract = "Light absorption due to transitions between the edge and two-dimensional (2D) states of a 2D topological insulator (TI) is considered in the Volkov-Pankratov model. It is shown that the transitions are allowed only for the in-plane electric field orthogonal to the TI edge. It is found that the absorption is accompanied by pure spin photocurrent along the TI edge. A possibility of spin current measurement using polarized luminescence from 2D TI quantum dots is discussed.",
