Abstract :
The method of FDTD solution of the full-wave vectorial Maxwell-Bloch equations for a two-level quantum system in 1D is applied to investigate the nonlinear gain spatio-temporal dynamics in an active semiconductor microcavity. The test structure used was 15 μm long active medium slab (GaAs) at the left boundary of which a continuous-wave sinusoid source field (after smooth turn-on within 5 periods) at the atomic transition frequency (λ = 1.5 μm) is launched.
