Abstract
We have studied the response of excitons in a multiple quantum-well structure under the presence of intense midinfrared fields. Peak fields in the plane of quantum wells) that would cause exciton quenching at low frequencies (up to are observed to have no significant quenching effect on the exciton resonance when applied at We attribute this lack of quenching to the short period of the strong, high-frequency field compared to the exciton response time.
