Nonlinearity-induced optical torque
Ivan Toftul, Gleb Fedorovich, Denis Kislov +4
Optically-induced mechanical torque leading to the rotation of small objects requires the presence of absorption or breaking cylindrical symmetry of a scatterer. A spherical non-ab…
When does nonlinear circular dichroism appear in achiral dielectric nanoparticles?
Anastasia Nikitina, Anna Nikolaeva, Kristina Frizyuk
Sometimes it appears, sometimes it does not. We present a theoretical study of circular dichroism in the second-harmonic signal of single dielectric nanostructures with different s…
Multipolar theory of bianisotropic response
Maria Poleva, Kristina Frizyuk, Kseniia Baryshnikova +3
Bianisotropy of metaatoms is usually associated with their nonlocal response and the mutual coupling between electric and magnetic dipole moments induced by the incident field. In…
Thermo-optical reshaping of SHG emission from dimerall-dielectric nanoresonators
Olesiya Pashina, Kristina Frizyuk, George Zograf +1
In recent years resonant semiconductor and all-dielectric nanophotonics offered a lot of possibilities for thermally-induced light manipulation at the nanoscale. Owing to high-qual…
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…
