Domain formation and self-sustained oscillations in quantum cascade lasers

Research output: Contribution to journalArticle

Abstract

Abstract: We study oscillations in quantum cascade lasers due to traveling electric field domains, which are observed both in simulations and experiments. These oscillations occur in a range of negative differential resistance and we clarify the condition determining whether the boundary between domains of different electric field can become stationary.
