Active Microparticle Media
Abstract
The theoretical and experimental research on the active nonlinear optical processes in the microparticle composites and conjugated polymers were investigated. The experimental studies focused on the transient effects in the phase conjugation and coherent beam combination using picosecond pulses. The theoretical studies emphasized the physical mechanisms of the nonlinear properties of the metallic microparticle composites and the conjugated polymers. Solid-state nonlocal continuum for the nonlinear electrodynamics of the microparticle composites was developed. A semiclassical lattice-dynamic theory was derived to predict the large nonresonant optical nonlinearity below the bandgap for one-dimensional conjugated polymers. This effort concentrated on the electronic nonlinearity of the microparticle composites and the conjugated polymers. The electronic nonlinearity is the most significant contribution for the picosecond pulse applications, which are useful in the high bit-rate transmission and communication.
