Thermo-optical bistability enabled by bound states in the continuum in silicon metasurfaces
Alexander Barulin, Olesia Pashina, Daniil Riabov +9
The control of light through all-optical means is a fundamental challenge in nanophotonics and a key effect in optical switching and logic. The optical bistability effect enables t…
Second-harmonic generation tuning by stretching arrays of GaAs nanowires
Grégoire Saerens, Esther Bloch, Kristina Frizyuk +7
We present a wearable device with III-V nanowires in a flexible polymer, which is used for active mechanical tuning of the second-harmonic generation intensity. An array of vertica…
Observation of an accidental bound state in the continuum in a chain of dielectric disks
M. S. Sidorenko, O. N. Sergaeva, Z. F. Sadrieva +4
Being a general wave phenomenon, bound states in the continuum (BICs) appear in acoustic, hydrodynamic, and photonic systems of various dimensionalities. Here, we report the first…
Dynamically reconfigurable metal-semiconductor Yagi-Uda nanoantenna
Roman S. Savelev, Olga N. Sergaeva, Denis G. Baranov +2
We propose a novel type of tunable Yagi-Uda nanoantenna composed of metal-dielectric (Ag-Ge) core-shell nanoparticles. We show that, due to the combination of two types of resonanc…
