Dark solitons in semiconductor resonators.
The properties of dark spatial solitons in a quantum well semiconductor resonator are investigated experimentally and by model calculations. We find experimentally and confirm theoretically that the solitons show local light amplification. The amount of amplification as well as its parameter dependence changes with the character of the nonlinearity (absorptive, dispersive, mixed). Theoretically a new ring-shaped dark soliton is found to exist.
