High-efficiency, 80-mm aperture metalens telescope
Lidan Zhang, Shengyuan Chang, Xi Chen +5
Metalenses, artificially engineered subwavelength nanostructures to focus light within ultrathin thickness, promise potential for a paradigm shift of conventional optical devices.…
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…
Single-Cavity Bi-Color Laser Enabled by Optical Anti-Parity-Time Symmetry
Yao Duan, Xingwang Zhang, Yimin Ding +1
The exploration of quantum-inspired symmetries in optical systems has spawned promising physics and provided fertile ground for developing devices exhibiting exotic functionalities…
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…
