Area of Science:

• Quantum Optics
• Optomechanics
• Condensed Matter Physics

Background:

• Hybrid optomechanical systems couple mechanical resonators to optical cavities and quantum systems.

Purpose of the Study:

• To theoretically investigate probe field transmission and group delay in a hybrid optomechanical system.
• To explore the switching between optomechanically induced transparency and absorption.
• To analyze the prolongation of group delay via mechanical driving fields.

Main Methods:

• Analysis of probe field transmission and group delay.
• Investigating the effects of control and mechanical driving fields, including their phase differences.

Main Results:

• Double optomechanically induced transparency can be switched to absorption via destructive interference.
• Amplification can occur due to constructive interference, dependent on field phase differences.
• Probe transmission is controllable by tuning optical and mechanical driving field parameters.
• Group delay of the probe field can be significantly prolonged by adjusting the mechanical driving field's amplitude and phase.

Conclusions:

• The hybrid optomechanical system offers tunable control over light propagation.
• Phase and amplitude of driving fields are key parameters for manipulating optical properties.
• This work provides insights for designing advanced optical devices and quantum information processing systems.
