Superradiance Effects in the Linear and Nonlinear Optical Response of Quantum Dot Molecules

We calculate the linear optical response from a single quantum dot molecule and the nonlinear, four-wave-mixing response from an inhomogeneously broadened ensemble of such molecules. We show that both optical signals are affected by the coupling-dependent superradiance effect and by optical interference between the two polarizations. As a result, the linear… CONTINUE READING
