The nonlinear optical response of Semiconductor Quantum Wells, Organic Superlattices and Conjugated Polyenes was calculated using collective electronic coordinates, which represent the joint dynamics of electron-hole pairs. The use of femtosecond four-wave mixing spectroscopy to probe the nature of electronic States and Exciton and free-carrier interactions in these systems was explored. The formation and dynamics of quasiparticles involving electrons dressed by nuclear deformations in conjugated polymers was studied. The Si natures of charged solitons, neutral solitons, polarons and bipolarons in the resonant and off-resonant optical susceptibilities of conjugated polymers were calculated using the Pariser-Parr-Pople (PPP) model. The optical response was obtained by solving equations of motion for the reduced single-electron density matrix, derived using the time dependent Hartree-Fock (TDHF) approximation. The approach relates the optical Signals directly to the dynamics of charges and bond orders (electronic coherences) induced by the radiation field and uses only ground-state information, thus avoiding the explicit calculation of excited states. A Density-Matrix-Electronic-Oscillator representation was employed for calculating the third order nonlinar A optical response of semiconductor quantum dots in the limits of weak and strong exciton confinement. The nonlocal electrodynamics of arrays of quantum dots was treated exactly using Green function techniques. The research program included the development of software which uses the newly developed algorithms in the design of new optical materials.
This book deals with basic physical properties related to the nonlinear interaction of light and matter. Nonlinear effects in atomic (molecular) systems and condensed matter are described, and classical phenomena as well as phenomena requiring a field-quantised description are covered. Leading authorities in nonlinear optics have reviewed themes of current interest in the research literature, and described general principles of importance for newcomers to the field.
The contributions of leading international experts assembled in this volume provide an authoritative description of current research in the highly topical area of the optical properties of semiconductor structures in the nanometer range. .
J-aggregates have a long history of research but so far no books have been published on this group of very interesting materials. The book is on the structures, electronic states, linear and nonlinear optical properties and spectroscopies of the J-aggregates. Various properties and processes of J-aggregates such as superradiance, excitons, photon echo, geometrical structure, electron transfer and femtosecond spectroscopy are also discussed. The contributors are those actively working in the field.
