Phase-dependent Supermode Excitation in Photonic Molecules
Yury E. Geints
A photonic molecule (PM) is a miniature diffractive optical structure composed of resonance microcavities called atoms (e.g., cylinders or spheres) supporting a set of high-quality…

Enhanced optical trapping assisted by resonant energy backflow in a perforated dielectric microsphere
Yury E. Geints, Igor V. Minin, Oleg V. Minin
Optical energy flow inside a dielectric microsphere exposed to an optical wave is usually codirected with its wave vector. At the same time, if the optical field in a microparticle…

Simulations of the filamentation and self-channeling of spatially modulated high-power femtosecond laser pulses in air
Yury Geints, Olga Minina, Alexander Zemlyanov
The propagation of high-power femtosecond laser pulses in air under conditions of superposed spatial phase modulation is considered theoretically. The numerical simulations are car…
