Opto-mechanical switch via enhanced luminality control

Abstract

We engineer opto-mechanical switch based on subluminal and superluminal behavior of transmission probe field. Our system includes strong driving field in a hybrid nano-electro-optomechnical system comprising two-level atoms and two charged mechanical resonators connected by bias voltages. We explain the parametric control on changing velocity of light in the Stokes and anti-Stokes sideband regimes. Moreover, we show that the group delay of pulse advancement is controlled experimentally by adjusting the electrostatic Coulomb coupling and power of driving field.We engineer opto-mechanical switch based on subluminal and superluminal behavior of transmission probe field.
