Fano resonance-assisted all-dielectric array for enhanced near-field optical trapping of nanoparticles
Donato Conteduca, Saba N. Khan, Manuel A. Martínez Ruiz +3
Near-field optics can overcome the diffraction limit by creating strong optical gradients to enable the trapping of nanoparticles. However, it remains challenging to achieve effici…
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…
An Ultra-high Numerical Aperture Metalens at Visible Wavelengths
Haowen Liang, Qiaoling Lin, Xiangsheng Xie +8
We demonstrate a metalens with NA = 0.98 in air, a bandwidth (FWHM) of 274 nm and a focusing efficiency of 67% at 532 nm wavelength, which is close to the transmission performance…
Highly effective relativistic free carrier plasma mirror confined within a silicon slow light photonic crystal waveguide
Mahmoud A. Gaafar, Dirk Jalas, Liam OFaolain +4
Reflection at relativistically moving plasma mirrors is a well-known approach for frequency conversion as an alternative to nonlinear techniques. A key issue with plasma mirrors is…
Optical performance monitoring at 640Gb/s via slow-light in a silicon nanowire
B. Corcoran, C. Monat, M. Pelusi +6
We demonstrate optical performance monitoring of in-band optical signal to noise ratio (OSNR) and residual dispersion, at bit rates of 40Gb/s, 160Gb/s and 640Gb/s, using slow-light…
