A theoretical model was presented for linear susceptibility using density matrix theory for Yconfiguration of double quantum dots (QDs) system including spontaneously generated coherence (SGC). Two SGC components are included for this system: V, and K subsystems. It is shown that at high V-component, the system have a giga gain. At low K-system component; it is possible to controls the light speed between superluminal and subluminal using one parameter by increasing SGC component of the V-system. This have applications in quantum information storage and spatially-varying temporal clock. (C) 2017 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY license.
