Abstract
The optical nonlinearity and dephasing dynamics of two-dimensional excitons in semi-conductor structures in which confined electromagnetic modes resonantly interact with the exciton are strongly modified compared with the bare exciton behavior. Quantum wells embedded in microcavities or excitons in multiple quantum well (MQW) Bragg samples, which consist of a large number N of identical quantum wells spaced by λ/2 (X is the wavelength of the excitonic transition in the medium), are typical examples.
