研究目的
Investigating the conversion process between radiation pressure and mechanical trapping potential engineered by the optical field in an optomechanical system.
研究成果
The study demonstrates that different mechanical potential modes can be switched on the order of microseconds in an optomechanical photonic molecule system. The findings suggest potential applications in quantum field effect transistors, quantum switches, and cold atom research, as well as in superlattices and quantum-well lasers.
研究不足
The study is theoretical and relies on numerical simulations based on parameters from recent experiments. Practical implementation may face challenges in tuning system parameters like decay rates and detunings precisely.
1：Experimental Design and Method Selection:
The study involves the theoretical illustration of an optomechanical photonic molecule system that provides different stiffer trapping potentials. The system's performance parameters are based on recent experiments, including linear optomechanical coupling coefficient and damping rate of mechanical oscillators.
2：Sample Selection and Data Sources:
The system consists of two directly edge coupled microtoroidal whispering-gallery mode resonators under the parity-time-symmetric condition.
3：List of Experimental Equipment and Materials:
The setup includes a gain/loss balanced optomechanical photonic molecule, microtoroidal whispering-gallery mode resonators, and fiber-tapers forming an add-drop structure.
4：Experimental Procedures and Operational Workflow:
The study numerically simulates the time required through the conversion process between different trapping potential modes, considering the condition that one of the modes approaches to steady state.
5：Data Analysis Methods:
The analysis involves numerical simulations to investigate the relationship between potential of the mechanical mode and the pumping electromagnetic field, and the conversion speed between different potential modes.
