Broadband on-chip Half Maxwell Fisheye
Xin Zheng, Quan Yue, Jean-René Coudevylle +4
In this article, we report on the design and the experimental evidence of a Half Maxwell Fish Eye (HMFE), for Silicon Photonics and working at telecommunication wavelength. It is d…
All-optical programming of polarization singularities in a photonic-crystal laser
Abhishek Padhy, Zhiyi Yuan, Mohammed Hamdad +11
Singular optics has emerged as an important research area with diverse applications, yet controlling optical singularities in nanophotonic emitters remains largely constrained by t…
Band Inversion Flips the Winding of Bound States in the Continuum
Paul Bouteyre, Dung Xuan Nguyen, Loïc Malgrey +10
Bound states in the continuum (BICs) in photonic slabs and metasurfaces appear as polarization singularities in momentum space, characterized by an integer winding number. This win…
Moiré Photonic Crystals: from Fabric to Magic
Marion Lavignac, Hai Son Nguyen, Xavier Letartre +2
Moiré patterns have recently become a very active field in nanophotonics. Those structures exhibit novel photonic properties unattainable with traditional photonic crystals. Espec…
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…
