Description
Summary:Recent advances in metasurfaces and optical nanostructures have enabled complex control of incident light with optically thin devices. However, it has thus far been unclear whether it is possible to achieve complete linear control of coherent light transmission, that is, independent control of polarization, amplitude, and phase for both input polarization states, with just a single, thin nanostructure array. Here, it is proved possible, and a universal metasurface is proposed, a bilayer array of high‐index elliptic cylinders that possesses a complete degree of optical freedom with fully designable chirality and anisotropy. The completeness of achievable light control is mathematically shown with corresponding Jones matrices, new types of 3D holographic schemes that were formerly impossible are experimentally demonstrated, and a systematic way of realizing any input‐state‐sensitive vector linear optical device is presented. The results unlock previously inaccessible degrees of freedom in light transmission control. T. Chang, J. Jung, S.‐H. Nam, H. Kim, J. U. Kim, N. Kim, S. Jeon, M. Heo, J. Shin It is proved that a bilayer nanostructure array is sufficient to completely control amplitudes, polarizations, and phases of coherent light transmission. Universal metasurfaces with such full control are realized with silicon nanostructures. A new kind of 3D vector hologram and a general platform for arbitrary optical transformation are demonstrated. This work provides another degree of freedom in light transmission control.
