  • The authors report the observation of diffraction-free space-time surface plasmon polaritons propagating along straight paths at metal-dielectric interfaces. This enhances the control of wavepacket propagation for nanophotonics applications.

  • Recently, the increased capabilities in generating pulsed optical fields that are rigidly transported in linear media without diffraction or dispersion has opened the path to realisation of 3D optical skyrmionic structures. Here, the authors demonstrate 3D-localized optical merons by imprinting polarization textures onto the momentum-energy space of ultrafast light pulses.

  • Researchers demonstrate a resonance-free Fabry-Perot cavity using a single holographic phase mask. By converting Gaussian input into a broadband mix of Laguerre-Gaussian modes, the cavity remains stable despite  ~350% length changes, paving the way for highly reliable optical sensors.

  • Propagation-invariant wave packets confined in space and time can be useful for optical sensing, imaging, and nonlinear and quantum optics. Here the authors demonstrate control over the angular dispersion of optical wave packets in two-transverse dimensions to synthesize space-time wave packets localized in all dimensions.

  • Delay lines are a critical part of future optical communications. Here, the authors create a delay line in free space by tuning the group velocities of multiple inline space-time wavepackets to introduce different delays.

  • Waveguides typically function by using boundary conditions to contain light. Here, the authors show that by using space-time wavepackets, light can be guided in an unpatterned planar waveguide as the field remains localized along the unbounded dimension.

  • An appropriately designed pulsed beam crossing an interface is shown to enable phenomena including anomalous group-velocity increase in higher-index materials, and tunable group velocity by varying the angle of incidence.
