Two-dimensional transition metal di-chalcogenide semiconductors provide unique possibil-ities to investigate strongly confined excitonic physics and a plasmonic platform integrable to such materials constitutes a hybrid system that can be of interest to enable manipulation of their cumulative optical properties. Here we report tuning of excitonic emission from monolayer WSe 2 , mechanically exfoliated on top of a periodic two dimensional plasmonic array of elliptical gold (Au) nanodiscs. By…

Second Harmonic Generation Covering the Entire Visible Range from a 2D Material–Plasmon Hybrid Metasurface

On‐chip coherent light source has always been fascinating and intriguing due to its various potential applications. In the past decades, there has been some progress in the development of chip

Strong coupling regime and hybrid quasinormal modes from a single plasmonic resonator coupled to a transition metal dichalcogenide monolayer

We present a rigorous photonic mode model to describe the strong coupling between a monolayer of MoSe2 and a single gold nanoparticle. The onset of strong coupling is quantified by computing the

Valleytronics in 2D materials

The energy extrema of an electronic band are referred to as valleys. In 2D materials, two distinguishable valleys can be used to encode information and explore other valleytronic applications.

Enhanced fields on rough surfaces: dipolar interactions among particles of sizes exceeding the Rayleigh limit

Amplified electromagnetic fields generated by a surface of finitely sized metal or dielectric particles are calculated. Regular arrays of particles produced by lithographic techniques and stochastic

Microcavity polaritons—the bosonic quasiparticles that result from strong light–matter coupling—are observed for the first time in a dielectric cavity containing a monolayer of molybdenum disulphide

Control of Strong Light-Matter Interaction in Monolayer WS2 through Electric Field Gating.

Modulation of strong exciton-photon coupling in a monolayer WS2 through electric field induced gating at room temperature to realize low energy optoelectronic switches and modulators operating both in quantum and classical regimes is demonstrated.

Coupling Single Photons from Discrete Quantum Emitters in WSe2 to Lithographically Defined Plasmonic Slot Waveguides.

By characterizing individual emitters, this work confirms their single-photon character via the observation of antibunching in the signal and demonstrates that specific emitters couple to modes of the proximal plasmonic waveguide.
