Metasurface-dressed two-dimensional on-chip waveguide for free-space light field manipulation
Yimin Ding, Xi Chen, Yao Duan +5
We show that a metasurface-coated two-dimensional (2D) slab waveguide enables the generation of arbitrary complex light fields by combining the extreme versatility and freedom on w…
Broadband Polarization-Independent Achromatic Metalenses with Unintuitively-Designed Random-Shaped Meta-Atoms
Xiaojie Zhang, Haiyang Huang, Xuexue Guo +6
Metasurface lenses, namely metalenses, are ultrathin planar nanostructures that are capable of manipulating the properties of incoming light and imparting lens-like wavefront to th…
Parametrically Excited Time-varying Metasurfaces for Second Harmonic Generation
Xuexue Guo, Xingjie Ni
Parametric oscillation is a fundamental concept that underlies nonlinear wave-matter interactions, leading to generation or amplification of new frequency components. Using a tempo…
Molding Free-Space Light with Guided-Wave-Driven Metasurfaces
Xuexue Guo, Yimin Ding, Xi Chen +2
Metasurfaces with unparalleled controllability of light have shown great potential to revolutionize conventional optics. However, they mainly work with free-space light input, whic…
Nonreciprocal Metasurface with Space-Time Phase Modulation
Xuexue Guo, Yimin Ding, Yao Duan +1
Creating materials with time-variant properties is critical for breaking reciprocity that imposes fundamental limitations to wave propagation. However, it is challenging to realize…
