Abstract

We theoretically investigated the optical response properties of the optical field in three-level quantum dot molecules assisted optomechanical system consisting of the mechanical resonator. We show that various system parameters like second-order optomechanical coupling can control these nonlinear effects. In this work, we study how the system parameters affect the normal mode splitting of the movable mirror and output field. Further, we show that the second-order optomechanical coupling plays an important role in creating optomechanical entanglement as well as producing a strong squeezing spectrum of the optical field.
