Background:

Metastable optically controlled devices, or optical flip-flops, are crucial for data storage, signal processing, and displays.
Existing nonvolatile optical data storage often relies on chalcogenide glasses, but weak optical nonlinearities limit low-power bistable device development.

Purpose of the Study:

To report a novel volatile optical bistability in a hybrid nano-optomechanical device.
To explore the potential of acoustically driven nanowires and plasmonic metamolecules for low-power optical switching.

Main Methods:

Fabrication of a hybrid nano-optomechanical device with anchored nanowires decorated with plasmonic metamolecules.
Utilizing acoustic waves to drive nanowire mechanics, influencing plasmonic metamolecule reconfiguration.
Optical power transduction of mechanical nonlinearity and bistability.

Main Results:

Demonstrated volatile optical bistability in the hybrid nano-optomechanical system.
Achieved switching between bistable optical states using microwatts of optical power.
Confirmed erasable volatile memory by removing the acoustic signal.

Conclusions:

The hybrid nano-optomechanical approach enables low-power optical bistability.
This technology opens new avenues for developing efficient optical flip-flops.
Potential applications in optical data storage, signal processing, and display technologies.
