Abstract

We calculated the optical nonlinearities of the atomically thin monolayer transition metal dichalcogenide material (particularly MoS₂), particularly for those linear and nonlinear transition processes that utilize the bound exciton states. We adopted the bound and the unbound exciton states as the basis for the Hilbert space, and derived all the dynamical density matrices that provides the induced current density, from which the nonlinear susceptibilities can be drawn order-by-order via perturbative calculations. We provide the nonlinear susceptibilities for the linear, the second-harmonic, the third-harmonic, and the kerr-type two-photon processes.

Optical nonlinearities of excitons in monolayer ${MoS}_{2}$

Journal Article Soh, Daniel; Rogers, Christopher; Gray, Dodd; ... - Physical Review B

We calculate linear and nonlinear optical susceptibilities arising from the excitonic states of monolayer MoS₂ for in-plane light polarizations, using second-quantized bound and unbound exciton operators. Optical selection rules are critical for obtaining the susceptibilities. We derive the valley-chirality rule for the second-order harmonic generation in monolayer MoS₂ and find that the third-order harmonic process is efficient only for linearly polarized input light while the third-order two-photon process (optical Kerr effect) is efficient for circularly polarized light using a higher order exciton state. The absence of linear absorption due to the band gap and the unusually strong two-photon third-order nonlinearitymore »« less

Tunable plasmon-enhanced second-order optical nonlinearity in transition metal dichalcogenide nanotriangles

Journal Article Karimi, Farhad; Soleimanikahnoj, S.; Knezevic, Irena - Physical Review. B

The development of nanomaterials with a large nonlinear susceptibility is essential for nonlinear nanophotonics. Here we show that transition metal dichalcogenide (TMD) nanotriangles have a large effective second-order susceptibility [χ⁽²⁾] at midinfrared to near-infrared frequencies owing to their broken centrosymmetry. χ⁽²⁾ is calculated within the density-matrix formalism that accounts for dissipation and screening. χ⁽²⁾ peaks in the vicinity of both two-photon resonances (specified by the geometry) and plasmon resonances (tunable via the carrier density). Aligning the resonances yields the values of χ⁽²⁾ as high as 10^–6 m/V. These findings underscore the potential of TMD nanotriangles for nonlinear nanophotonics, particularly second-harmonicmore » generation.« less

Integrating Plasmonic Metals and 2D Transition Metal Dichalcogenides for Enhanced Nonlinear Frequency Conversion

Conference Dunklin, Jeremy; Forcherio, Gregory; Bonacina, Luigi; ...

Surface plasmon resonant nanoantennas can confine incident energy onto two-dimensional (2D) transition metal dichalcogenides (TMD) to enhance efficiency of harmonic conversion to higher energies, which is otherwise limited by the intrinsic A-scale interaction length. Second harmonic generation (SHG) from nanoantenna-decorated 2D TMD was heuristically examined with hyper Rayleigh scattering (HRS), multi-photon microscopy, electron energy loss spectroscopy (EELS), and discrete dipole computation. HRS experimentally quantified the frequency dependence of the second-order nonlinear susceptibility, x(2), for liquid-exfoliated WS2. Measured x(2) fell within 21% of independent density functional theory (DFT) calculations, overcoming the known 100-1000x overestimation of microscopy approaches. EELS supported design ofmore »« less

Colloquium: Excitons in atomically thin transition metal dichalcogenides

Journal Article Wang, Gang; Chernikov, Alexey; Glazov, Mikhail; ... - Reviews of Modern Physics

Atomically thin materials such as graphene and monolayer transition metal dichalcogenides (TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality and crystal symmetry. The family of semiconducting transition metal dichalcogenides is an especially promising platform for fundamental studies of two-dimensional (2D) systems, with potential applications in optoelectronics and valleytronics due to their direct band gap in the monolayer limit and highly efficient light-matter coupling. A crystal lattice with broken inversion symmetry combined with strong spin-orbit interactions leads to a unique combination of the spin and valley degrees of freedom. In addition, the 2D character of the monolayers and weakmore »« less

Linear and Nonlinear Optical Properties of Metal Nanocomposite Materials

Technical Report Haglund, Jr., Richard

The scientific theme of this award stated in its title is “Linear and Nonlinear Optical Properties of Metal Nanoparticle Composites.” The motivation for the proposal was based on prior work that highlighted unusual third-order nonlinear optical response of metal-nanoparticle composites created by Vanderbilt researchers at the Oak Ridge National Laboratory (ORNL) by implanting metal ions into fused-silica and sapphire substrates and annealing them under appropriate conditions to produce a solid solution comprising noble-metal nanoparticles embedded in an insulating matrix. For example, the well-known localized surface plasmon resonance (LSPR) of gold and silver nanoclusters and nanoparticles was known to yield enhancedmore »« less
