Unified Weak-to-Strong Coupling Transitions and Radiation Interference Induced by Vertical-Symmetry Breaking in Photonic Crystal Slabs
Huy Hoang Chu, Raphael Mermet-Lyaudoz, Florian Dubois +10
Vertical-symmetry breaking provides a versatile means of coupling leaky photonic-crystal resonances that are otherwise protected by opposite out-of-plane parity. Here, we develop a…
Multi-wavelength UV Upconversion in Lanthanides assisted by Photonic Crystals
Damien Rinnert, Emmanuel Drouard, Antonio Pereira +6
Upconversion luminescence consists of the absorption of low-energies photons followed by the emission of a higher energy photon. The process has mainly been studied in lanthanides…
Tailoring Flatband Dispersion in Bilayer Moiré Photonic Crystals
Chirine Saadi, Sébastien Cueff, Lydie Ferrier +6
In this study, we experimentally investigate the photonic dispersion in one-dimensional moiré structures formed by stacking two photonic crystal slabs with slightly different peri…
