Broadband field-enhancement in epsilon-near-zero photonic gap antennas
Félix Thouin, David M. Myers, Ashutosh Patri +3
In recent years, the large electric field enhancement and tight spatial confinement supported by the so-called epsilon-near-zero (ENZ) mode have attracted significant attention for…
Stochastic scattering theory for excitation induced dephasing: Time-dependent nonlinear coherent exciton lineshapes
Ajay Ram Srimath Kandada, Hao Li, Félix Thouin +2
We develop a stochastic theory that treats time-dependent exciton-exciton s-wave scattering and that accounts for dynamic Coulomb screening, which we describe within a mean-field l…
Electron-phonon couplings inherent in polarons drive exciton dynamics in two-dimensional metal-halide perovskites
Félix Thouin, Ajay Ram Srimath Kandada, David A. Valverde-Chávez +6
We report on the exciton formation and relaxation dynamics following photocarrier injection in a single-layer two-dimensional lead-iodide perovskite. We probe the time evolution of…
Enhanced screening and spectral diversity in many-body elastic scattering of excitons in two-dimensional hybrid metal-halide perovskites
Félix Thouin, Daniele Cortecchia, Annamaria Petrozza +2
In two-dimensional hybrid organic-inorganic metal-halide perovskites, the intrinsic optical lineshape reflects multiple excitons with distinct binding energies, each dressed differ…
Phonon coherences reveal the polaronic character of excitons in two-dimensional lead-halide perovskites
Félix Thouin, David A. Valverde Chávez, Claudio Quarti +6
Hybrid organic-inorganic semiconductors feature complex lattice dynamics due to the ionic character of the crystal and the softness arising from non-covalent bonds between molecula…
End-to-end Deep Learning of Optical Fiber Communications
Boris Karanov, Mathieu Chagnon, Félix Thouin +5
In this paper, we implement an optical fiber communication system as an end-to-end deep neural network, including the complete chain of transmitter, channel model, and receiver. Th…
