“…One prominent application is the modification of the propagation of a light pulse through an atomic medium, which depends on the dispersive properties of the medium. The study of such pulse propagation phenomena has been triggered by a series of papers by Sommerfeld and Brillouin [2,3] and continues to be of much interest [4,5,6,7,8,9]. It is well known that the group velocity of a light pulse can be slowed down [10,11], can become faster than its value c in vacuum, or can even become negative [12,13].…”

Abstract. The propagation of a weak probe field in a laser-driven four-level atomic system is investigated. We choose mercury as our model system, where the probe transition is in the ultraviolet region. A high-resolution peak appears in the optical spectra due to the presence of interacting dark resonances. We show that this narrow peak leads to superluminal light propagation with strong absorption, and thus by itself is only of limited interest. But if in addition a weak incoherent pump field is applied to the probe transition, then the peak structure can be changed such that both sub-and superluminal light propagation or a negative group velocity can be achieved without absorption, controlled by the incoherent pumping strength.Group velocity control in the ultraviolet domain via interacting dark-state resonances 2

“…Such systems can exhibit quantum coherence and interference effects, e.g., enhanced nonlinear effects [1], electromagnetically induced transparency (EIT) [2][3][4], giant Kerr nonlinearity [5][6][7], lasing without inversion [8][9][10], efficient nonlinear frequency conversions [11,12], coherence Raman scattering enhancement via maximum coherence in atoms [13] and molecules [14], enhanced lasing [15,16], coherent Raman umklappscattering [17], photodesorption [18] to name a few. Recently quantum coherence effects has been applied to a new domain on plasmonics and shown to benefit nanophotonics [19,20].…”
