Terahertz excitation of three-level Λ-type exciton-polariton modes in quantum-well microcavity

Terahertz excitation of three-level Λ-type exciton-polariton modes in quantum-well microcavity

Interactions of strong few-cycle THz pulses with the induced optical polarization in a quantum-well microcavity reveal that the exciton-polariton modes and the 2p-exciton state form a unique Λ-type three-level system of the coupled light-matter modes.
