Optical Generation and Control of Quantum Coherence in Semiconductor Nanostructures available in PDF, EPUB and Kindle. The fundamental concept of quantum coherence plays a central role in quantum physics, cutting across disciplines of quantum optics, atomic and condensed matter physics. Quantum coherence represents a universal property of the quantum s- tems that applies both to light and matter thereby tying together materials and p- nomena. Moreover, the optical coherence can be transferred to the medium through the light-matter interactions. Since the early days of quantum mechanics there has been a desire to control dynamics of quantum systems. The generation and c- trol of quantum coherence in matter by optical means, in particular, represents a viable way to achieve this longstanding goal and semiconductor nanostructures are the most promising candidates for controllable quantum systems. Optical generation and control of coherent light-matter states in semiconductor quantum nanostructures is precisely the scope of the present book. Recently, there has been a great deal of interest in the subject of quantum coh- ence. We are currently witnessing parallel growth of activities in different physical systems that are all built around the central concept of manipulation of quantum coherence. The burgeoning activities in solid-state systems, and semiconductors in particular, have been strongly driven by the unprecedented control of coherence that previously has been demonstrated in quantum optics of atoms and molecules, and is now taking advantage of the remarkable advances in semiconductor fabrication technologies. A recent impetus to exploit the coherent quantum phenomena comes from the emergence of the quantum information paradigm.

An understanding of the interaction between light and matter on a quantum level is of fundamental interest and has many applications in optical technologies. The quantum nature of the interaction has recently attracted great attention for applications of semiconductor nanostructures in quantum information processing. Quantum optics with semiconductor nanostructures is a key guide to the theory, experimental realisation, and future potential of semiconductor nanostructures in the exploration of quantum optics.Part one provides a comprehensive overview of single quantum dot systems, beginning with a look at resonance fluorescence emission. Quantum optics with single quantum dots in photonic crystal and micro cavities are explored in detail, before part two goes on to review nanolasers with quantum dot emitters.

Optical Control and Detection of Spin Coherence in Semiconductor Nanostructures available in PDF, EPUB and Kindle. Understanding the coherent dynamics of electron spins in quantum dots (QDs) is important for potential applications in solid-state, spin-based electronics and quantum information processing. Here, results are presented focusing on optical initialization, manipulation, and readout of spin coherence in various semiconductor nanostructures. Layered semiconductor nanocrystals are fabricated containing a spherical "quantum shell" in which electrons and holes are confined. As in a planar quantum well, the quantized energy levels and g-factors are found to depend on the shell thickness. Taking this idea a step further, nanocrystals with a concentric, tunnel-coupled core and shell are investigated. Based on the energy and g-factor dependences in these structures, spins can be selectively initialized into, and read out from, states in the core and shell. In contrast to these two ensemble measurements, we next turn to measurements of single electron spins in single QDs. First, we demonstrate the detection of a single electron spin in a QD using a nondestructive, continuously averaged magneto-optical Kerr rotation (KR) measurement. This continuous single QD KR technique is then extended into the time domain using pulsed pump and probe lasers, allowing the observation of the coherent evolution of an electron spin state with nanosecond temporal resolution. By sweeping the delay between the pump and probe, the dynamics of the spin in the QD are mapped out in time, providing a direct measurement of the electron g-factor and spin lifetime. Finally, this time-resolved single spin measurement is used to observe ultrafast coherent manipulation of the spin in the QD using an off-resonant optical pulse. Via the optical Stark effect, this optical pulse coherently rotates the spin state through angles up to pi radians, on picosecond timescales.

The potential for implementing quantum coherence in semiconductor self-assembled quantum dots has been investigated theoretically and experimentally. Theoretical modeling suggests that coherent dynamics should be possible in self-assembled quantum dots. Our experimental efforts have optimized InGaAs and InAs self-assembled quantum dots on GaAs for demonstrating coherent phenomena. Optical investigations have indicated the appropriate geometries for observing quantum coherence and the type of experiments for observing quantum coherence have been outlined. The optical investigation targeted electromagnetically induced transparency (EIT) in order to demonstrate an all optical delay line.
