摘要： A broadband photon echo effect in a three level Λ-type system interacting with two laser fields is investigated theoretically. Inspired by the emerging field of nuclear quantum optics which typically deals with very narrow resonances, we consider broadband probe pulses that couple to the system in the presence of an inhomogeneous control field. We show that such a setup provides an all-electromagnetic-field solution to implement high bandwidth photon echoes, which are easy to control, store and shape on a short time scale and, therefore, may speed up future photonic information processing. The time compression of the echo signal and possible applications for quantum memories are discussed. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society (APS) 出版日期： 2014-09-19 出處： Physical Review Letters, 2014-09, Vol.113 (12), p.123602, Article 123602 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/physrevlett.113.123602 識別號： PMID: 25279629
