| Popis: | In this thesis we study transient absorption in two quantum dot systems under the conditions of optical transparency. We will study two types of transparency; the first is voltage-controlled transparency and the second electromagnetically induced transparency. The thesis starts with a short introduction in quantum dot nanostructures that is followed by an introduction to the phenomenon and the history of electromagnetically induced transparency. We then study the coherent interaction of the electromagnetic fields with the quantum dots with the methodology of the density matrix that is analysed in the thesis. We solve the appropriate density matrix equations numerically for the structures under study and present results for several system parameters. |
