Correction of aberrations via polarization in single layer metalenses
Augusto Martins, Kezheng Li, Guilherme S. Arruda +6
The correction of multiple aberrations in an optical system requires different optical elements, which increases its cost and complexity. Metasurfaces hold great promise to providi…
Metalenses with polarization-independent adaptive nano-antennas
Jianchao Zhang, Haowen Liang, Yong Long +8
Metalens research has made major advances in recent years. These advances rely on the simple design principle of arranging meta-atoms in regular arrays to create an arbitrary phase…
Optical Push Broom On a Chip
Mahmoud A. Gaafar, He Li, Xinlun Cai +3
Here we report the first experimental demonstration of light trapping by a refractive index front in a silicon waveguide, the optical push broom effect. The front generated by a fa…
Room temperature nanocavity laser with interlayer excitons in 2D heterostructures
Yuanda Liu, Hanlin Fang, Abdullah Rasmita +7
Atomically thin layered two dimensional (2D) material has provided a rich library for both fundamental research and device applications. One of the special advantages is that, band…
Fano resonance lineshapes in a waveguide-microring structure enabled by an air-hole
Linpeng Gu, Liang Fang, Hanlin Fang +5
We propose and demonstrate, by simply inserting an air-hole in the waveguide side-coupling with a microring resonator (MRR), the transmission spectrum presents Fano lineshapes at a…
Second harmonic and sum-frequency generations from a silicon metasurface integrated with a two-dimensional material
Qingchen Yuan, Liang Fang, Hanlin Fang +5
Silicon-based nonlinear metasurfaces were implemented only with third-order nonlinearity due to the crystal centrosymmetry and the efficiencies are considerably low, which hinders…
