Metasurface engineering through bound states in the continuum
Anton S. Kupriianov, Yi Xu, Andrey Sayanskiy +3
Metasurfaces have attracted a lot of attention in recent years due to novel ways they provide for the efficient wavefront control and engineering of the resonant transmission. We d…
Isotropic Magnetic Purcell Effect
Tianhua Feng, Wei Zhang, Zixian Liang +2
Manipulating the spontaneous emission rate of optical emitters with all-dielectric nanoparticles benefits from their low-loss nature and thus provides relatively large extrinsic qu…
Unidirectional emission in an all-dielectric nanoantenna
Tianhua Feng, Wei Zhang, Zixian Liang +1
All-dielectric nanoantennas are a promising alternative to plasmonic optical antennas for engineering light emission because of their low-loss nature in the optical spectrum. Never…
Ideal magnetic dipole scattering
Tianhua Feng, Yi Xu, Wei Zhang +1
We introduce the concept of tunable ideal magnetic dipole scattering, where a nonmagnetic nanoparticle scatters lights as a pure magnetic dipole. High refractive index subwavelengt…
Reconfigurable nonreciprocity with nonlinear Fano diode
Yi Xu, Andrey E. Miroshnichenko
We propose a dynamically tunable nonreciprocal response for wave propagations by employing nonlinear Fano resonances. We demonstrate that transmission contrast of waves propagation…
Compact surface Fano states embedded in the continuum of waveguide arrays
Steffen Weimann, Yi Xu, Robert Keil +5
We describe theoretically and observe experimentally the formation of a surface state in a semi-infnite waveguide array with side-coupled waveguide, designed to simultaneously achi…
Nonlinear Mach-Zehnder-Fano interferometer
Yi Xu, Andrey E. Miroshnichenko
We demonstrate that the interaction of loop and nonlinear Fano resonances results in a formation of hybrid resonant states in Mach-Zehnder type interferometers, providing with oppo…
