Optical metasurfaces consist of 2D arrangements of scatterers, and they control the
amplitude, phase, and polarization of an incidence field on demand. Optical metasurfaces …

In this work, an all‐dielectric photonic metasurface with a flat macroscopic geometry is
shown to provide a viable solution toward realization of a relativistic light sail driven by …

A lightsail accelerated via directed energy is a candidate technology to send a probe into the
deep space in a time period compatible with human life. The light emitted by a ground …

The photonic propulsion of lightsails can be used to accelerate spacecraft to relativistic
velocities, providing a feasible route for the exploration of interstellar space in the human …

We report ultrathin photonic metagratings where anisotropic scattering is designed to
achieve self-stabilizing dynamics in a collimated beam of laser light. Stability necessitates a …
