Optoplasmonic whispering‐gallery‐mode (WGM) microcavities, consisting of plasmonic nanostructures and optical microcavities, provide excellent platforms for exploring fundamental mechanisms as well as facilitating novel optoplasmonic applications. These integrated systems support hybrid modes with both subwavelength mode confinement and high‐quality factor which do not exist in either pure optical WGM microcavities or plasmonic resonators. In this progress report, geometric designs and fabrication strategies of optoplasmonic microcavities, which efficiently bridge the interaction between resonant light and plasmonic resonances, are reviewed in detail. Three types of hybrid modes in the optoplasmonic microcavities, that is, surface‐plasmon‐polariton whispering‐gallery modes, hybrid photon–plasmon whispering‐gallery modes, and heterostructured metal–dielectric whispering‐gallery modes, are considered. These modes are characterized by a largely enhanced evanescent field that is referred to as a plasmon‐type field in hybrid whispering‐gallery modes. Moreover, the coupling effect between localized surface plasmon resonances and whispering‐gallery modes is summarized. The underlying coupling mechanisms and their influence on mode shifts, Q factor, mode splitting, and line shapes of the whispering‐gallery modes are discussed. Applications based on optoplasmonic WGM microcavities including enhanced sensing, nanolasing, and free‐space coupling are highlighted, followed by an outlook of the opportunities and challenges in developing large‐scale on‐chip integrated optoplasmonic systems.

“…Here we propose a simple way to understand the main points by analyzing a much simpler and yet related case, that is a hybrid system of a low Q plasmonic nano-antenna coupled with a high Q photonic microcavity. [32] These systems were recently addressed as a viable method to profit from both the small modal volume of plasmonic resonator and the high Q of the photonic microcavities. At the same time, we reckon that the very lossy plasmonic QNM acts as an effective background continuum of states for the high Q cavity, so we expect to understand some general rules linking the features of the continuum with the resulting value of q n and q ′ n of the n-th QNMs of a photonic system in Equations ( 3) and (4).…”

The spectral and spatial dependence of the resonant Lamb shift of an exciton inside a photonic vacuum field landscape is considered to predict an optical dipole potential generated via virtual photons quantum fluctuations. This trapping potential can be exploited for exciton self-positioning in electric field hotspots at the nanoscale in view of quantum electrodynamics effects. By non Hermitian decomposition of the electromagnetic Green tensor in terms of quasi normal modes, the resonant part of the Lamb shift is expressed as Fano profile strictly interlinked to the Purcell enhancement of the exciton radiative lifetime. This approach explains how to tailor the depth of the vacuum photonic potential in several possible scenarios.

Molecular optomechanics describes surface-enhanced Raman scattering using the formalism of cavity optomechanics as a parametric coupling of the molecule’s vibrational modes to the plasmonic resonance. Most of the predicted applications require intense electric field hotspots but spectrally narrow resonances, out of reach of standard plasmonic resonances. The Fano lineshapes resulting from the hybridization of dielectric–plasmonic resonators with a broad-band plasmon and narrow-band cavity mode allow reaching strong Raman enhancement with high- Q resonances, paving the way for sideband resolved molecular optomechanics. We extend the molecular optomechanics formalism to describe hybrid dielectric–plasmonic resonators with multiple optical resonances and with both free-space and waveguide addressing. We demonstrate how the Raman enhancement depends on the complex response functions of the hybrid system, and we retrieve the expression of Raman enhancement as a product of pump enhancement and the local density of states. The model allows prediction of the Raman emission ratio into different output ports and enables demonstrating a fully integrated high- Q Raman resonator exploiting multiple cavity modes coupled to the same waveguide.
