TL;DR

This paper demonstrates that light-induced forces in graphene waveguides are highly tunable and significantly stronger than in traditional devices, enabling advanced control and modulation in nano- and micro-scale optomechanical systems.

Contribution

It reveals that electromagnetic forces in graphene-based systems can be tuned via chemical potential and are much stronger than in non-graphene devices, with potential for enhanced optomechanical control.

Findings

Forces are highly tunable by chemical potential.

Forces are orders of magnitude stronger than in non-graphene devices.

Potential for advanced control and fast modulation in nano- and micro-scale systems.

Abstract

We show that the electromagnetic forces generated by the excitations of a mode in graphene-based optomechanical systems are highly tunable by varying the graphene chemical potential, and orders of magnitude stronger than usual non-graphene-based devices, in both attractive and repulsive regimes. We analyze coupled waveguides made of two parallel graphene sheets, either suspended or supported by dielectric slabs, and study the interplay between the light-induced force and the Casimir-Lifshitz interaction. These findings pave the way to advanced possibilities of control and fast modulation for optomechanical devices and sensors at the nano- and micro-scales.
