Femtosecond Coherent Emission From Gaas Bulk Microcavities
PHYSICAL REVIEW B(1999)
摘要
The emission from a lambda/2 GaAs bulk microcavity resonantly excited by femtosecond pulses has been characterized by using an interferometric correlation technique. It is found that the emission is dominated by the coherent signal due to light elastically scattered by disorder, and that scattering is predominantly originated from the lower polariton branch.
