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…
Super Bound States in the Continuum on Photonic Flatbands: Concept, Experimental Realization, and Optical Trapping Demonstration
Ngoc Duc Le, Paul Bouteyre, Ali Kheir-Aldine +7
In this work, we theoretically propose and experimentally demonstrate the formation of a super bound state in a continuum (BIC) on a photonic crystal flat band. This unique state s…
Tailoring the Local Density of Optical States and directionality of light emission by symmetry-breaking
Sébastien Cueff, Matthew Shao Ran Huang, Dongfang Li +4
We present a method to simultaneously engineer the energy-momentum dispersion and the local density of optical states. Using vertical symmetry-breaking in high-contrast gratings, w…
Directional lasing at high oblique angle from metasurface exhibiting multivalley dispersion
Hai Son Nguyen, Florian Dubois, Thierry Deschamps +5
We report on a metasurface laser emitting at the valley extremum of a multivalley energy-momentum dispersion. Such peculiar dispersion shape is obtained by hybridizing high quality…
Symmetry Breaking in Photonic Crystals: On-Demand Dispersion from Flatband to Dirac Cones
Hai Son Nguyen, Florian Dubois, Thierry Deschamps +6
We demonstrate that symmetry breaking opens a new degree of freedom to tailor the energy-momentum dispersion in photonic crystals. Using a general theoretical framework in two illu…
