“…Reaching GHz frequencies requires further scaling the devices to sub-pg masses. This would involve photonic structures with moving parts with dimensions of few tens of nm, and correspondingly a field confinement at these scales, which, for typical nearinfrared wavelengths, can only be achieved in plasmonic structures 7,8 or in slotted photonic crystals 9,10 .…”

A new class of hybrid systems that couple optical, electrical and mechanical degrees of freedom in nanoscale devices is under development in laboratories worldwide. These nano-opto-electromechanical systems (NOEMS) offer unprecedented opportunities to dynamically control the flow of light in nanophotonic structures, at high speed and low power consumption. Drawing on conceptual and technological advances from cavity optomechanics, they also bear the potential for highly efficient, low-noise transducers between microwave and optical signals, both in the classical and quantum domains. This Progress Article discusses the fundamental physical limits of NOEMS, reviews the recent progress in their implementation, and suggests potential avenues for further developments in this field.2

“…The resonant frequencies of these modes depend sensitively on the nanostructures' geometric configuration such as the gap size between interacting elements1011. Accordingly, strong coupling of light to nanomechanical motion can be realized by introducing a mechanical degree of freedom into the plasmonic structure1213141516. Plasmomechanical systems based on this principle have been suggested for applications in reconfigurable metamaterials12, compact optical switches13 and sensors, enabling optical motion readout in nanoelectromechanical systems (NEMS) as well as dynamic light manipulation by NEMS17.…”

Plasmonic structures couple oscillating electromagnetic fields to conduction electrons in noble metals and thereby can confine optical-frequency excitations at nanometre scales. This confinement both facilitates miniaturization of nanophotonic devices and makes their response highly sensitive to mechanical motion. Mechanically coupled plasmonic devices thus hold great promise as building blocks for next-generation reconfigurable optics and metasurfaces. However, a flexible approach for accurately batch-fabricating high-performance plasmomechanical devices is currently lacking. Here we introduce an architecture integrating individual plasmonic structures with precise, nanometre features into tunable mechanical resonators. The localized gap plasmon resonators strongly couple light and mechanical motion within a three-dimensional, sub-diffraction volume, yielding large quality factors and record optomechanical coupling strength of 2 THz·nm−1. Utilizing these features, we demonstrate sensitive and spatially localized optical transduction of mechanical motion with a noise floor of 6 fm·Hz−1/2, representing a 1.5 orders of magnitude improvement over existing localized plasmomechanical systems.

In the past decade, dynamic, tunable, compact, and fast plasmonic switches with high modulation depth (MD) and low losses have been developed successfully for various practical applications. Here, using a simple plasmonic dimer consisting of a pair of metallic nanodisks bridged to each other with a graphene monolayer, we develop a highly tunable plasmonic switch for telecommunication applications. We have shown that having active control on the photoconductivity of graphene sheet through electrical bias allows for transition of charges across the atomically thin bridge, giving rise to formation of charge transfer plasmon (CTP) modes. Such an interplay between semiconducting and semi‐metallic states of the graphene sublayer leads to direct control of the excited CTPs. By tuning the peak of CTP at the global telecommunication band (λ = 1550 nm), we designed an integrated, fast, and functional optoelectronic nanoswitch with high MD up to ≈98% and negligible losses. This study presents a promising approach to design tunable, high‐quality, integrated optoelectronic switches for next‐generation advanced nanophotonic applications.
