Accessing Chern Numbers From Bloch Eigenstates Singularities
Rajesh Asapanna, Rabih El Sokhen, Paolo Aceto +7
We propose two methods to extract the Chern numbers of the Bloch bands of a two dimensional insulator, and apply them to a photonic lattice experiment. These two methods require th…
Line lasing in a two-dimensional lattice of orbital photonic resonators
Tony Mathew Blessan, Bastian Real, Marijana Milicevic +8
The engineering of specialty lasers with unconventional mode structures is one of the modern challenges in the development of integrated coherent sources. Examples include the use…
Emission of time-ordered photon pairs from a coherently-driven Kerr microcavity
Ferdinand Claude, Yueguang Zhou, Sylvain Ravets +8
Weakly-interacting many-body systems possess remarkable quantum properties that are essential components of quantum technologies, and constitute a topic of fundamental interest. He…
Measuring non-Abelian quantum geometry and topology in a multi-gap photonic lattice
Martin Guillot, Cédric Blanchard, Martina Morassi +8
Recent discoveries in semi-metallic multi-gap systems featuring band singularities have galvanized enormous interest in particular due to the emergence of non-Abelian braiding prop…
All-optical nonlinear phase modulation in open semiconductor microcavities
Fedor A. Benimetskiy, Paul M. Walker, Anthony Ellul +8
We report a significant advancement in ultra low power light-by-light phase modulation using open semiconductor microcavities in the strong light-matter coupling regime. We achieve…
Directional transport and nonlinear localization of light in a one-dimensional driven-dissipative photonic lattice
Tony Mathew Blessan, Bastián Real, Camille Druelle +11
Photonic lattices facilitate band structure engineering, supporting both localized and extended modes through their geometric design. However, greater control over these modes can…
