Hybrid Epsilon-Near-Zero Modes of Photonic Gap Antennas
Ashutosh Patri, Kévin G. Cognée, David M. Myers +3
We demonstrate that in photonic gap antennas composed of an epsilon-near-zero (ENZ) layer embedded within a high-index dielectric, hybrid modes emerge from the strong coupling betw…
Photonic Gap Antennas Based on High Index-Contrast Slot-Waveguides
Ashutosh Patri, Kévin G. Cognée, Louis Haeberlé +3
Optical antennas made of low-loss dielectrics have several advantages over plasmonic antennas, including high radiative quantum efficiency, negligible heating and excellent photost…
Mid-infrared polarized emission from black phosphorus light-emitting diodes
Junjia Wang, Adrien Rousseau, Mei Yang +3
The mid-infrared (MIR) spectral range is of immense use for civilian and military applications. The large number of vibrational absorption bands in this range can be used for gas s…
Spectral responsivity and photoconductive gain in thin film black phosphorus photodetectors
Junjia Wang, Adrien Rousseau, Elad Eizner +4
We have fabricated black phosphorus photodetectors and characterized their full spectral responsivity. These devices, which are effectively in the bulk thin film limit, show broadb…
Time-resolved imaging of non-diffusive carrier transport in long-lifetime halide perovskite thin films
Aravindan Sridharan, Nakita K. Noel, Hyeon Hwang +3
Owing to their exceptional semiconducting properties, hybrid inorganic-organic perovskites show great promise as photovoltaic absorbers. In these materials, long-range diffusion of…
Triplet harvesting in the polaritonic regime: a variational polaron approach
Luis A. Martínez-Martínez, Elad Eizner, Stéphane Kéna-Cohen +1
We explore the electroluminescence efficiency for a quantum mechanical model of a large number of molecular emitters embedded in an optical microcavity. We characterize the circums…
Inverting Singlet and Triplet Excited States using Strong Light-Matter Coupling
Elad Eizner, Luis A. Martínez-Martínez, Joel Yuen-Zhou +1
In organic microcavities, hybrid light-matter states can form with energies that differ from the bare molecular excitation energies by nearly 1 eV. A timely question, given recent…
Organic Photodiodes with an Extended Responsivity using Ultrastrong Light-Matter Coupling
Elad Eizner, Julien Brodeur, Fábio Barachati +2
In organic photodiodes (OPDs) light is absorbed by excitons, which dissociate to generate photocurrent. Here, we demonstrate a novel type of OPD in which light is absorbed by polar…
Tunable third-harmonic generation from polaritons in the ultrastrong coupling regime
Fábio Barachati, Janos Simon, Yulia A. Getmanenko +2
Strong inter-particle interactions between polaritons have traditionally stemmed from their exciton component. In this work, we impart a strong photonic nonlinearity to a polariton…
Room-temperature superfluidity in a polariton condensate
Giovanni Lerario, Antonio Fieramosca, Fábio Barachati +8
Superfluidity---the suppression of scattering in a quantum fluid at velocities below a critical value---is one of the most striking manifestations of the collective behaviour typic…
Dynamical instability of a non-equilibrium exciton-polariton condensate
Nataliya Bobrovska, Michał Matuszewski, Konstantinos S. Daskalakis +2
By imaging single-shot realizations of an organic polariton quantum fluid, we observe the long-sought dynamical instability of non-equilibrium condensates. Without any free paramet…
Generation of Rabi frequency radiation using exciton-polaritons
Fábio Barachati, Simone De Liberato, Stéphane Kéna-Cohen
We study the use of exciton-polaritons in semiconductor microcavities to generate radiation spanning the infrared to terahertz regions of the spectrum by exploiting transitions bet…
Optical and Structural Properties of Ultra-thin Gold Films
Anna Kossoy, Virginia Merk, Denis Simakov +3
Realizing laterally continuous ultra-thin gold films on transparent substrates is a challenge of significant technological importance. In the present work, formation of ultra-thin…
Strong light-matter coupling in two-dimensional atomic crystals
Xiaoze Liu, Tal Galfsky, Zheng Sun +5
Two dimensional (2D) atomic crystals of graphene, and transition metal dichalcogenides have emerged as a class of materials that show strong light-matter interaction. This interact…
Microscopic Theory of Polariton Lasing via Vibronically Assisted Scattering
Leonardo Mazza, Stéphane Kéna-Cohen, Paolo Michetti +1
Polariton lasing has recently been observed in strongly coupled crystalline anthracene microcavities. A simple model is developed describing the onset of the non-linear threshold b…
