Abstract
Section titled āAbstractāThe weak probe pulse propagation is demonstrated in a solid-state system filled with diamond germanium-vacancy (GeV) defect centers under optical excitation. We find that the form of pulse propagation could be greatly manipulated by the probe-detuning, control-detuning, the control fieldās intensity and the GeV centers density due to quantum coherence. It shows that the pulse can propagate without diffusion and attenuation because of electromagnetically induced transparency (EIT) under appropriate parameters in this solid scheme. Our results perhaps are helpful in actual tests to realize the optical computing and optical storage devices in a quantum nanophotonic platform.
