Mode‐Locked Pulse Generation in Plasmonic Lattices
Laser &Photonics Reviews, EarlyView.The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate
Laser &Photonics Reviews, EarlyView.Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
Laser &Photonics Reviews, EarlyView.The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.
