Journal ArticleDOI
Metalenses at visible wavelengths: Diffraction-limited focusing and subwavelength resolution imaging.
Mohammadreza Khorasaninejad,Wei Ting Chen,Robert C. Devlin,Jaewon Oh,Alexander Y. Zhu,Federico Capasso +5 more
TL;DR: The results firmly establish that metalenses can have widespread applications in laser-based microscopy, imaging, and spectroscopy, with image qualities comparable to a state-of-the-art commercial objective.
Journal ArticleDOI
A broadband achromatic metalens for focusing and imaging in the visible.
Wei Ting Chen,Alexander Y. Zhu,Vyshakh Sanjeev,Vyshakh Sanjeev,Mohammadreza Khorasaninejad,Zhujun Shi,Eric Lee,Eric Lee,Federico Capasso +8 more
TL;DR: It is shown that by judicious design of nanofins on a surface, it is possible to simultaneously control the phase, group delay and group delay dispersion of light, thereby achieving a transmissive achromatic metalens with large bandwidth.
Journal ArticleDOI
High-efficiency broadband anomalous reflection by gradient meta-surfaces.
Shulin Sun,Kuang-Yu Yang,Chih Ming Wang,Ta Ko Juan,Wei Ting Chen,Chun Yen Liao,Qiong He,Shiyi Xiao,Wen Ting Kung,Guang-Yu Guo,Guang-Yu Guo,Lei Zhou,Din Ping Tsai,Din Ping Tsai +13 more
TL;DR: This work combines theory and experiment to demonstrate that a carefully designed gradient meta-surface supports high-efficiency anomalous reflections for near-infrared light following the generalized Snell's law, and the reflected wave becomes a bounded surface wave as the incident angle exceeds a critical value.
Journal ArticleDOI
High-Efficiency Broadband Meta-Hologram with Polarization-Controlled Dual Images
Wei Ting Chen,Kuang-Yu Yang,Chih Ming Wang,Yao-Wei Huang,Greg Sun,I-Da Chiang,Chun Yen Liao,Wei-Lun Hsu,Hao Tsun Lin,Shulin Sun,Lei Zhou,Ai Qun Liu,Din Ping Tsai,Din Ping Tsai +13 more
TL;DR: The flexibility demonstrated here for the meta-hologram paves the road to a wide range of applications related to holographic images at arbitrary electromagnetic wave region.
Journal ArticleDOI
Polarization-Insensitive Metalenses at Visible Wavelengths
Mohammadreza Khorasaninejad,Alexander Y. Zhu,Charles Roques-Carmes,Charles Roques-Carmes,Wei Ting Chen,Jaewon Oh,Jaewon Oh,Ishan Mishra,Ishan Mishra,Robert C. Devlin,Federico Capasso +10 more
TL;DR: These metalenses are less than 600 nm-thick and can focus incident light down to diffraction-limited spots as small as ∼0.64λ and provide high-resolution imaging, which makes them highly promising for widespread applications in imaging and spectroscopy.
