Planar Microcavities can Suppress Exciplex Formation and Increase the Emission Efficiency of Organic Semiconductors
Tomohiro Ishii, Stéphane Kéna-Cohen
Optical microcavities are widely used to control the emission of organic semiconductors, but their ability to reshape the molecular pathways that precede emission remains largely u…
Enhanced nonlinear interaction of polaritons via excitonic Rydberg states in monolayer WSe2
Jie Gu, Valentin Walther, Lutz Waldecker +7
Strong optical nonlinearities play a central role in realizing quantum photonic technologies. In solid state systems, exciton-polaritons, which result from the hybridization of mat…
Large-Angle, Broadband and Multifunctional Gratings Based on Directively Radiating Waveguide Scatterers
Ashutosh Patri, Stephane Kena-Cohen, Christophe Caloz
Conventional surface-relief gratings are inefficient at deflecting normally-incident light by large angles. This constrains their use in many applications and limits the overall ef…
Compact grating coupler using asymmetric waveguide scatterers
Ashutosh Patri, Xiao Jia, Muhammad Mohsin +2
We demonstrate a novel grating coupler design based on double asymmetric and vertically oriented waveguide scatterers to efficiently couple normally incident light to a fundamental…
Interacting polariton fluids in a monolayer of tungsten disulfide
Fábio Barachati, Antonio Fieramosca, Soroush Hafezian +7
Atomically thin transition metal dichalcogenides (TMDs) possess a number of properties that make them attractive for realizing room-temperature polariton devices. An ideal platform…
Polariton-assisted Singlet Fission in Acene Aggregates
Luis A. Martínez-Martínez, Matthew Du, Raphael F. Ribeiro +2
Singlet fission is an important candidate to increase energy conversion efficiency in organic photovoltaics by providing a pathway to increase the quantum yield of excitons per pho…
Quantum Statistics of Surface Plasmon Polaritons in Metallic Stripe Waveguides
Giuliana Di Martino, Yannick Sonnefraud, Stéphane Kéna-Cohen +4
Single surface plasmon polaritons are excited using photons generated via spontaneous parametric down-conversion. The mean excitation rates, intensity correlations and Fock state p…
