Light emitters in vicinity of a hyperbolic metamaterial (HMM) show a range of quantum optical phenomena from spontaneous decay rate enhancement to strong coupling. In this study, we integrate monolayer Molybdenum disulfide (MoS 2 ) emitter in near field region of HMM. The MoS 2 monolayer has A and B excitons, which emit in the red region of visible spectrum. We find that the B excitons couple to HMM differently compared to A excitons. The fabricated HMM transforms to a hyperbolic dispersive medium at ≃ 2.13 eV, from an elliptical dispersive medium. The selective coupling of B Excitons to the HMM modes is attributed to the inbuilt field gradient of the transition. The B exciton energy lies close to the transition point of the HMM, relative to A Exciton. So, the HMM modes couple more to the B excitons and the metamaterial functions as selective coupler. The coupling strength calculations show that coupling is 2.5 times stronger for B excitons relative to A excitons. High near field of HMM, large magnitude and the in-plane transition dipole moment of MoS 2 Excitons, result in strong coupling of B excitons and formation of hybrid light-matter states. The measured differential Reflection and Photoluminescence spectra indicate the presence of hybrid light-matter states i.e. Exciton-Polaritons. Rabi splitting of

Light emitters in the vicinity of a hyperbolic metamaterial (HMM) show a range of quantum optical phenomena from spontaneous decay-rate enhancement to strong coupling. In this study, we integrate a monolayer molybdenum disulfide (MoS 2 ) emitter in the near-field region of the HMM. The MoS 2 monolayer has A and B excitons, which emit in the red region of the visible spectrum. We find that the B excitons couple to the HMM differently compared to A excitons. The fabricated HMM transforms to a hyperbolic dispersive medium at 2.14 eV, from an elliptical dispersive medium. The selective coupling of B excitons to the HMM modes is attributed to the inbuilt field gradient of the transition. The B exciton energy lies close to the transition point of the HMM, relative to the A exciton. So, the HMM modes couple more to the B excitons and the metamaterial functions as a selective coupler. The coupling strength calculations show that coupling is 2.5 times stronger for B excitons relative to A excitons. High near field of HMM, large magnitude, and the in-plane transition dipole moment of MoS 2 excitons, result in strong coupling of B excitons and formation of hybrid light-matter states. The measured differential reflection and photoluminescence spectra indicate the presence of hybrid light-matter states, i.e., exciton polaritons. Rabi splitting of 143.5 meV ± 14.4 meV at room temperature is observed. The low-temperature photoluminescence measurement shows mode anticrossing, which is a characteristic feature of hybrid states. Our results show that the HMM works as an energy-selective coupler for multiexcitonic systems as MoS 2 .

“…Strong coupling was first demonstrated with a single Rydberg atom in a microwave cavity, and strong coupling to a single emitter has remained an important area of focus since it opens new possibilities for studying a variety of light–matter interactions, like single atom lasing , and quantum entanglement . Since the first experimental demonstration, strong coupling has been demonstrated in a variety of systems, primarily focusing on emitters located near metamaterials or within microcavities and photonic crystals. ,− Strong coupling of quantum dot emitters near an HMM has also been demonstrated . However, strong coupling has yet to be demonstrated between the bulk large wavevector modes, the VPPs, in an HMM and an embedded emitter or absorber.…”

Strong Coupling in Semiconductor Hyperbolic Metamaterials

Semiconductor-based layered hyperbolic metamaterials (HMMs) house high-wavevector volume plasmon polariton (VPP) modes in the infrared spectral range. VPP modes have successfully been exploited in the weak-coupling regime through the enhanced Purcell effect. In this paper, we experimentally demonstrate strong coupling between the VPP modes in a semiconductor HMM and the intersubband transition of epitaxially embedded quantum wells. We observe clear anticrossings in the dispersion curves for the zeroth-, first-, second-, and third-order VPP modes, resulting in upper and lower polariton branches for each mode. This demonstration sets the stage for the creation of novel infrared optoelectronic structures combining HMMs with embedded epitaxial emitter or detector structures.
