Abstract


We demonstrate that the weak optical absorption in a thin layer of QDs can be overcome for certain frequencies and angles of incidence by interference of the light reflected at the different sample interfaces. This phenomenon, known as coherent perfect absorption, can be used to enhance the luminescence emission of the QD layer.
