Ideal Optomechanically Induced Transparency and Amplification Based on Nonrotating Wave Approximation Effect
In the cavity photomechanical system including the two-level atom ensemble, the neglected non-rotating wave approximation effect is used to discuss the optically induced transparency, dispersion and optically induced amplification in the unsolvable and solvable sideband regions nature. When the driving light field is red detuning, the perfect optically induced transparency and optically induced amplification can be achieved in the solvable and unsolvable sideband regions, respectively. The experimental results show that the full width at half maximum of the optically induced transparent window becomes very narrow with the increase of the dissipation rate of the optically mechanical cavity in both the solvable and the unsolvable sideband regions, but the full width at half maximum of the optically induced transparent window in the unsolvable sideband region is much smaller than that in the solvable sideband region. The change of the maximum value of photo induced amplification is just opposite to the change of the full width at half maximum of the photo induced transparent window. The maximum value of photo induced amplification in the solvable sideband region is less than that in the unsolvable sideband region.
