A microscopic theory for the terahertz response of excited semiconductor systems is presented. It is verified that the theory yields the correct effective‐mass Drude limit. For a fully interacting incoherent system, the terahertz response is shown to be determined by the electron–hole correlations. The theory is evaluated for the example of excitonic populations in a quantum‐well structure.
