THEORY OF NON-MARKOVIAN OPTICAL GAIN IN QUANTUM-WELL LASERS

摘要

Semiconductor quantum-well lasers have been an interesting subject of research for more than a decade both from the fundamental and the application points of view. The electrons and holes in quantum-wells in the presence of the strong optical field form a many-body Fermion system accompanied by nonequilibrium distributions with characteristic dynamical Relaxations~(1-4). These relaxation kinetics in nonequilibrium systems are often characterized By the presence of memory effects on a very short time scale and the equations of motion For the system have time-convolution forms of integral kernels which are responsible for the Memory effects~(5-8).
