Metasurface-Based Multidimensional Light-Field Manipulation: From Technologies to Applications. [PDF]

open access: yesAdv Sci (Weinh)
Multidimensional metasurfaces enable versatile manipulation of multiple optical degrees of freedom, including phase, amplitude, polarization, wavelength, and orbital angular momentum. This review summarizes their fundamental mechanisms, emerging strategies for multidimensional light‐field control, and key applications in optical computing, imaging ...

Simulated holographic three-dimensional intensity shaping of evanescent-wave fields [PDF]

open access: yes, 2008
The size of bright structures in traveling-wave light fields is limited by diffraction. This in turn limits a number of technologies, for example, optical trapping.
