Theory of ultrafast spatio-temporal dynamics in semiconductor heterostructures Original Research Article

Non-stationary spatio-temporal effects in semiconductor heterostructures are investigated for optical excitation by solving the coupled Semiconductor Maxwell-Bloch equations where relaxation processes are treated on the level of quantum kinetic equations in the Markovian limit. Light propagation in quantum well waveguide structures and perpendicular to multiple quantum wells is analysed in the case of linear and nonlinear response.
