✦ Synopsis

Dedicated to Professor Dr. Roland Zimmermann on the occasion of his 60th birthday Advances in nanoscopic probing techniques have led to the development of direct spatial and spectroscopic mapping methodologies which have revealed a wealth of information about single quantum dots. These techniques, combined with the favorable properties of naturally formed quantum dots, have allowed us to treat a single exciton confined to a quantum dot as a single solid state quantum absorber in analogy to atomic and molecular systems. Direct measurements on these systems, including absorption and coherent nonlinear spectroscopy, have revealed dipole moments and dynamic time scales of the individual excitations. Combined with microscopy, these probes have revealed global properties of the quantum dot system.
