Taming Friedrich-Wintgen interference in resonant metasurface: vortex laser emitting at on-demand tilted-angle
Raphael Mermet-Lyaudoz, Clémentine Symond, Florian Berry +7
Friedrich-Wintgen (FW) interference is an atypical coupling mechanism that grants loss exchange between leaky resonances in non-Hermitian classical and quantum systems. Intriguingl…
Enhanced self-phase modulation in silicon nitride waveguides integrated with 2D graphene oxide films
Yuning Zhang, Jiayang Wu, Yunyi Yang +9
We experimentally demonstrate enhanced self-phase modulation (SPM) in silicon nitride (Si3N4) waveguides integrated with 2D graphene oxide (GO) films. GO films are integrated onto…
Analytical non-Hermitian description of Photonic Crystals with arbitrary Lateral and Transverse symmetry
X. Letartre, S. Mazauric, S. Cueff +3
In this work we propose a general theoretical approach to the modelling of complex dispersion characteristics of leaky optical modes operating in photonic crystal slab composed of…
Unveiling the Enhancement of Spontaneous Emission at Exceptional Points
Lydie Ferrier, Paul Bouteyre, Adi Pick +10
Exceptional points (EPs), singularities of non-Hermitian physics where complex spectral resonances degenerate, are one of the most exotic features of nonequilibrium open systems wi…
