Exciton-Tunable Phase Control and Superstrong Coupling Through Multimode Polariton Engineering in Planar Waveguides
Johannes Bürger, Erika Cortese, Simone Di Muzio +3
Strong light-matter coupling in optical waveguides provides a versatile platform for engineering hybrid polaritonic modes and their dispersion. Here we investigate multimode excito…
Fully Integrated Perovskite Polaritonic Circuits with Tunable Lasing and Nonlinear Amplification
Antonio Fieramosca, Vincenzo Ardizzone, Rosanna Mastria +17
Photonic integrated circuits are emerging as a key technology for compact and energy-efficient optical information processing. Yet, their practical implementation remains limited b…
Microfluidic-Assisted Growth of Perovskite Microwires for Room-Temperature All-Optical Switching Based on Total Internal Reflection
Annalisa Coriolano, Antonio Fieramosca, Laura Polimeno +8
The development of efficient integrated photonic circuits is fundamental for ongoing research in information processing and computer science. The greatest challenge in strong light…
Directional optical parametric amplification in a hyperbolic metamaterial
Antonio Gianfrate, Dimitrios Trypogeorgos, Paolo Comaron +5
Optical parametric amplification (OPA) comprises essentially a nonlinear four-wave mixing process in which a "pump" and a "signal" field give rise to an "idler" field under certain…
Condensation dynamics in a two-dimensional photonic crystal waveguide
Maria Efthymiou-Tsironi, Antonio Gianfrate, Dimitrios Trypogeorgos +6
Exciton-polariton condensation occurs at the extrema of the underlying dispersion where the density of states diverges and carriers can naturally accumulate. The existence of multi…
Geometric control of hyperbolic exciton-polariton condensate dimers
Ioannis Georgakilas, Antonio Gianfrate, Dimitrios Trypogeorgos +7
Coupled many-body quantum systems exhibit rich emergent physics with diverse stationary and dynamical behaviors. By engineering platforms with tunable and distinct coupling mechani…
