The author describes in this dissertation his work to conduct a wide range of frequency-domain coherent multi-color multidimensional experiments in the femtosecond time regime. A software platform, COLORS, was developed in the LabVIEW environment to calibrate and control tunable light sources, motorized optical delay stages, spectrometers, and data acquisition cards. To take advantage of the hardware control, automated routines were composed to conduct linear and multidimensional frequency, delay, and Wigner experiments. The software was designed with three principles in mind: minimalism, modularity, and extensibility. The author demonstrates the use of COLORS to conduct state-of-the-art multidimensional experiments on two nanomaterial systems--colloidal PbSe quantum dots and a few-layer thin-film of MoS2. In the PbSe studies, three-photon echo peak shift (3PEPS) and transient-grating experiments observed rapid ∼70-fs relaxation dynamics occurring within the 1S excitonic lineshape. These dynamics suggested the presence of fine structure that was inconsistent with the Particle-in-a-Sphere model of electronic structure under quantum confinement. The homogeneous and inhomogeneous contributions to the 1S excitonic linewidth were found to be ∼450 and ∼600 cm-1, respectively. Transient-grating studies performed in reflective geometry on a few-layer thin-film of MoS2 revealed the rapid appearance after excitation of a spectral cross-peak between the A and B excitons. If excitation was at or above the B excitonic feature, strong cross-peaks were created from hot A and B excitons as they underwent ultrafast intraband population transfer. Excitation below the B excitonic feature created a weak cross-peak, indicating an A-induced bleach of the B transition. Population relaxation occurred over ∼680 fs, either by transfer to traps or by bimolecular charge recombination.

This book will fulfill the needs of time-domain spectroscopists who wish to deepen their understanding of both the theoretical and experimental features of this cutting-edge spectroscopy technique. Coherent Multidimensional Spectroscopy (CMDS) is a state-of-the-art technique with applications in a variety of subjects like chemistry, molecular physics, biochemistry, biophysics, and material science. Due to dramatic advancements of ultrafast laser technologies, diverse multidimensional spectroscopic methods utilizing combinations of THz, IR, visible, UV, and X-ray radiation sources have been developed and used to study real time dynamics of small molecules in solutions, proteins and nucleic acids in condensed phases and membranes, single and multiple excitons in functional materials like semiconductors, quantum dots, and solar cells, photo-excited states in light-harvesting complexes, ions in battery electrolytes, electronic and conformational changes in charge or proton transfer systems, and excess electrons and protons in water and biological systems.

Reducing the size of a coherently grown semiconductor cluster in all three directions of space to a value below the de Broglie wavelength of a charge carrier leads to complete quantization of the energy levels, density of states, etc. Such “quantum dots” are more similar to giant atoms in a dielectric cage than to classical solids or semiconductors showing a dispersion of energy as a function of wavevector. Their electronic and optical properties depend strongly on their size and shape, i.e. on their geometry. By designing the geometry by controlling the growth of QDs, absolutely novel possibilities for material design leading to novel devices are opened. This multiauthor book written by world-wide recognized leaders of their particular fields and edited by the recipient of the Max-Born Award and Medal 2006 Professor Dieter Bimberg reports on the state of the art of the growing of quantum dots, the theory of self-organised growth, the theory of electronic and excitonic states, optical properties and transport in a variety of materials. It covers the subject from the early work beginning of the 1990s up to 2006. The topics addressed in the book are the focus of research in all leading semiconductor and optoelectronic device laboratories of the world.

This book introduces recent advances in the deterministic design of photonic structures, which overcome the current limitation in conventional disordered materials. It develops new concepts for disordered photonics inspired by notions in quantum mechanics, solid-state physics, mathematics and network theory, such as isospectrality, supersymmetry, graph network, small-world, de Broglie-Bohm theory, and parity-time symmetry. The multidisciplinary approach based on the core concepts of isospectrality (Chapter 2) and metadisorder (Chapter 3) offers a new perspective on the design methodology in photonics and in general disordered structures toward top-down designs of future photonic applications: perfect bandgap with strong modal localization, switching of random waves for binary and fuzzy logics, photonic analogy of graph networks, interdimensional signal transport, robust wave functions in disordered structures, and a novel method of energy storage and phase trapping based on Bohmian photonics. This book will provide new design criteria for physicists and engineers in photonics, and inspirations for researchers in other fields.
