WebApr 5, 2024 · In some recent studies, gain assisted schemes have been suggested to obtain superluminal light propagation and anomalous dispersion [1, 21, 22]. Ziauddin and Qamar [23] have used a two photon Raman gain process for the coherent control of the Goos–Hanchen shift in a fixed atomic structure. However, these Raman gain systems … WebJul 26, 2024 · Here, we study dispersion and absorption properties of a weak probe field in a Landau-quantized graphene and report a gain-assisted superluminal light propagation.
