TRR 142 - Nonlinear optics in quantum dot molecules (C03)
Overview
In this project, nonlinear optical effects in InGaAs quantum dot molecules (QPM) are investigated. The goal is to use the QPM as a frequency converter. To this end, absorbed photons excite an exciton complex, which is transformed into another complex by applied voltage pulses on nanosecond and picosecond time scales as charges are transferred between quantum dots. The Coulomb interaction and Pauli blockade between the charge carriers creates a nonlinearity, thereby enabling conditional dynamics.
