Modelling Purcell enhancement of metasurfaces supporting quasi-bound states in the continuum
Joshua T. Y. Tse, Taisuke Enomoto, Shunsuke Murai +1
Bound states in the continuum (BIC) exhibit extremely high quality factors due to the lack of radiation loss and thus are widely studied for Purcell enhancement. However, a closer…
Interpreting Purcell Enhancement of Non-Hermitian Metasurfaces with Spectral Parameters
Joshua T. Y. Tse, Shunsuke Murai, Katsuhisa Tanaka
The Purcell effect describes the enhancement of the spontaneous emission rate of an emitter near a resonant structure. However, evaluating the Purcell factor quantitatively and emp…
Modified Coupled-mode Theory for the Absorption in Plasmonic Lattices
Joshua T. Y. Tse, Shunsuke Murai, Katsuhisa Tanaka
Surface lattice resonance supported on plasmonic nanoparticle arrays enhances light-matter interactions for applications such as photoluminescence enhancement. The photoluminescenc…
Resonant Critical Coupling of Surface Lattice Resonances with Fluorescent Absorptive Thin Film
Joshua T. Y. Tse, Shunsuke Murai, Katsuhisa Tanaka
Surface lattice resonance supported on nanoparticle arrays is a promising candidate in enhancing fluorescent effects in both absorption and emission. The optical enhancement provid…
Room Temperature Exciton-Polariton Condensation in Silicon Metasurfaces Emerging from Bound States in the Continuum
Anton Matthijs Berghuis, Gabriel W. Castellanos, Shunsuke Murai +6
We show the first experimental demonstration of room-temperature exciton-polariton (EP) condensation from a bound state in the continuum (BIC). This demonstration is achieved by st…
Engineering bound states in the continuum at telecom wavelengths with non-Bravais lattices
Shunsuke Murai, Diego R. Abujetas, Libei Liu +5
Various optical phenomena can be induced in periodic arrays of nanoparticles by the radiative coupling of the local dipoles in each particle. Probably the most impressive example i…
Collective Mie Exciton-Polaritons in an Atomically Thin Semiconductor
Shaojun Wang, T. V. Raziman, Shunsuke Murai +6
Optically induced Mie resonances in dielectric nanoantennas feature low dissipative losses and large resonant enhancement of both electric and magnetic fields. They offer an altern…
Enhanced light emission by magnetic and electric resonances in dielectric metasurfaces
Shunsuke Murai, Gabriel W. Castellanos, T. V. Raziman +2
We demonstrate an enhanced emission of high quantum yield molecules coupled to dielectric metasurfaces formed by periodic arrays of polycrystalline silicon nanoparticles. Radiative…
Enhanced Delayed Fluorescence in Tetracene Crystals by Strong Light-Matter Coupling
Matthijs Berghuis, Alexei Halpin, Quynh Le-Van +4
We demonstrate experimentally an enhanced delayed fluorescence in tetracene single crystals strongly coupled to optical modes in open cavities formed by arrays of plasmonic nanopar…
Light-emitting waveguide-plasmon polaritons
S. R. K. Rodriguez, S. Murai, M. A. Verschuuren +1
We demonstrate the generation of light in an optical waveguide strongly coupled to a periodic array of metallic nanoantennas. This coupling gives rise to hybrid waveguide-plasmon p…
