Twist tunable resonances in photonic bilayer for second harmonic generation
Egor S. Vyatkin, Sergey A. Tarasenko
The paper presents an analytical theory for how twisting photonic bilayers creates tunable moiré resonances that can dramatically enhance second harmonic generation when integrated…

Resonant enhancement of second harmonic generation in 2D nonlinear crystal integrated with meta-waveguide: analytical vs numerical approaches
Egor S. Vyatkin, Sergey A. Tarasenko
We present an analytical theory of second harmonic generation (SHG) in hybrid structures combining a nonlinear 2D crystal with a dielectric metasurface waveguide. The theory descri…

Emergent spin and orbital angular momentum of light in twisted photonic bilayer
Egor S. Vyatkin, Alexander V. Poshakinskiy, Sergey A. Tarasenko
We demonstrate that the optical response of twisted photonic bilayers, photonic counterparts of van der Waals structures, is sensitive to both spin angular momentum (SAM) and orbit…
