Thin film aluminum nitride on insulator (AlNOI) has gained attention as a promising material platform for integrated photonic circuits (PICs) due to its ability to operate over a wide spectral range covering the ultra-violet to mid-infrared regions,

Realization of Bound state In the Continuum induced by vertical symmetry breaking in photonic lattice

Autor: Mermet-Lyaudoz, Raphael, Dubois, Florian, Hoang, Ngoc-Vu, Drouard, Emmanuel, Berguiga, Lotfi, Seassal, Christian, Letartre, Xavier, Viktorovitch, Pierre, Nguyen, Hai Son

We demonstrate experimentally a new type of Bound state In the Continuum (BIC) which is induced by the vertical symmetry breaking of a photonic crystal slab. Such BIC emerges from the hybridization between Bloch resonances of opposite parities once t

Super Bound States in the Continuum on Photonic Flatbands: Concept, Experimental Realization, and Optical Trapping Demonstration

Autor: Le, Ngoc Duc, Bouteyre, Paul, Kheir-Aldine, Ali, Dubois, Florian, Cueff, Sébastien, Berguiga, Lotfi, Letartre, Xavier, Viktorovitch, Pierre, Benyattou, Taha, Nguyen, Hai Son

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 simultaneously exhibits an enhanced quality factor and near-zero group

Directional lasing at high oblique angle from metasurface exhibiting multivalley dispersion

Autor: Nguyen, Hai Son, Dubois, Florian, Deschamps, Thierry, Cueff, Sébastien, Regreny, Philippe, Leclercq, Jean-Louis, Letartre, Xavier, Viktorovitch, Pierre

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 factor photonic modes of different symmetry and opposite effective ma

Symmetry Breaking in Photonic Crystals: On-Demand Dispersion from Flatband to Dirac Cones

Autor: Nguyen, Hai Son, Dubois, Florian, Deschamps, Thierry, Cueff, Sébastien, Pardon, Antonin, Leclercq, Jean-Louis, Seassal, Christian, Letartre, Xavier, Viktorovitch, Pierre

Publikováno v: Phys. Rev. Lett. 120, 066102 (2018)

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 illustrative practical structures, we show that breaking symmetry enables
