Inverse design of focused vector beams for mode excitation in optical nanoantennas
Xiaorun Zang, Ari T. Friberg, Tero Setälä +1
We propose a free-space, inverse design of nanostructure's effective mode-matching fields via a backward propagation of tightly focused vector beams to the pupil plane of an aplana…
Efficient hybrid-mode excitation in plasmonic nanoantennas by tightly focused higher-order vector beams
Xiaorun Zang, Godofredo Bautista, Léo Turquet +3
Efficient optical excitation of hybridized plasmon modes in nanoantennas is vital to achieve many promising functionalities, but it can be challenging due to a field-profile mismat…
Less is more - enhancement of second-harmonic generation from metasurfaces by reduced nanoparticle density
Robert Czaplicki, Antti Kiviniemi, Mikko J. Huttunen +7
We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In con…
Interaction between atoms and slow light: a waveguide-design study
Xiaorun Zang, Jianji Yang, Rémi Faggiani +8
The emerging field of on-chip integration of nanophotonic devices and cold atoms offers extremely-strong and pure light-matter interaction schemes, which may have profound impact o…
Theoretical treatment of the interaction between two-level atoms and periodic waveguides
Xiaorun Zang, Philippe Lalanne
Light transport in periodic waveguides coupled to a two-level atom is investigated. By using optical Bloch equations and a photonic modal formalism, we derive semi-analytical expre…
Lower bound for the spatial extent of localized modes in photonic-crystal waveguides with small random imperfections
Rémi Faggiani, Alexandre Baron, Xiaorun Zang +8
Light localization due to random imperfections in periodic media is paramount in photonics research. The group index is known to be a key parameter for localization near photonic b…
