Quantum optics by design

The effects of quantum optical effects in engineered semiconductor structures was analyzed. The effects of quantum optics are most cleanly seen in appropriate atomic or molecular systems, where well-defined energy level cascades can be prepared or dressed with narrowband and powerful pump laser fields. In these semiconductor nanostructures, the energy bands split into subbands with energy separations of several tens to a few hundreds of millielectronvolts large. In addition to the proper energy level sequence and narrow bandwidth, these semiconductor nanostructures also have much larger optical dipoles than molecular systems.
