We describe the recent experimental progress in the control of spontaneous emission by
manipulating optical modes with photonic crystals. It has been clearly demonstrated that the …

In recent years, the technology of optical communication has gained importance due to high
bandwidth and data rate requirements. This book focuses on free-space optical (FSO) …

Direct epitaxial integration of III-V materials on Si offers substantial manufacturing cost and
scalability advantages over heterogeneous integration. The challenge is that epitaxial …

Cavity quantum electrodynamics (QED) systems allow the study of a variety of fundamental
quantum-optics phenomena, such as entanglement, quantum decoherence and the …

Cavity quantum electrodynamics, a central research field in optics and solid-state physics,,,
addresses properties of atom-like emitters in cavities and can be divided into a weak and a …

including molecules,,, mesoscopic quantum wells, colour centres, trapped ions and …

The fine structure of excitons is studied by magnetophotoluminescence spectroscopy of
single self-assembled In (Ga) As/(Al) GaAs quantum dots. Both strength and orientation of …

The concept of the photon, central to Einstein's explanation of the photoelectric effect, is
exactly 100 years old. Yet, while photons have been detected individually for more than 50 …

Entangled photon pairs are an important resource in quantum optics, and are essential for
quantum information applications such as quantum key distribution, and controlled quantum …
