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…
Near-field light-bending photonic switch: physics of switching based on three-dimensional Poynting vector analysis
Liyang Yue, Zengbo Wang, Bing Yan +4
Photonic hook is a high-intensity bent light focus with a proportional curvature to the wavelength of the incident light. Based on this unique light-bending phenomenon, a novel nea…
Dynamics of femtosecond synthesized coronary profile laser beams filamentation in air
Yu. E. Geints, A. A. Zemlyanov
Multiple filamentation in air of high-power ultrashort laser radiation with transverse intensity profile resembling a "corona" composed by incoherent combining of several annularly…
Overcoming optical contrast limit of mesoscale light focusing by means of retrograde-reflection photonic nanojet
Yury E. Geints, Alexander A. Zemlyanov, Igor V. Minin +1
The physical origin of subwavelength photonic nanojet in retrograde-reflection mode (retro-PNJ) is theoretically considered. This specific type of photonic nanojet emerges upon seq…
