AI Article Synopsis
- The study explores polariton multistability in an optomechanical resonator that includes a quantum well and nonlinear medium.
- The coupling between excitonic transitions and optical cavity modes results in bistable behavior, which can shift to tristability with increased nonlinearity.
- The system's tunability is enhanced through control of coupling parameters, allowing for tristability at low input power, making it promising for low-power polaritonic devices.
Article Abstract
We theoretically study the polariton multistability in a solid state based optomechanical resonator embedded with a quantum well and asecond order nonlinear medium. The excitonic transition inside the quantum well is strongly coupled to the optical cavity mode. The polariton formed due to the mixing of cavity photons and exciton states are coupled to the mechanical mode which gives rise to the bistable behavior. A transition from bistability to tristability occurs in the presence of a strongnonlinearity. Switching between bistability and tristability can also be controlled using exciton-cavity and optomechanical coupling making the system highly tunable. Tristability appears at low input power making it a suitable candidate for polaritonic devices which requires low input power.
