TL;DR: In this paper , a one-dimensional photonic crystal, with a high index inclusion in the top layer, that sustains surfaces modes with, in principle, arbitrary polarization is presented.

TL;DR: In this article , a non-local spin-current injection, manipulation, and detection in n-doped bulk Si at room temperature is presented, where spins are locally generated at the indirect gap of bulk Si by means of circularly polarized light and then detected by exploiting the inverse spin-Hall effect (ISHE) occurring inside a thin Pt pad deposited at the top of the Si substrate.

TL;DR: In this article, a nonlinear aperture SNOM is used to acquire high-peak intensity femtosecond (LSP) light pulses in the near field from single gold nanoellipsoids with various aspect ratios.

TL;DR: In this paper , a nonlinear periodic metasurface is employed to perform all-optical routing of telecom photons upconverted to the visible range. This is achieved via interference between two frequency-degenerate upconversion processes, namely third-harmonic and sum-frequency generation.

TL;DR: In this paper, a spin polarized excitons population is selectively created in a single valley by circularly polarized ultrashort laser pulses resonant with the optical gap, while the subsequent decay of the valley polarization is measured as a rotation of a linearly polarized probe beam due to a transient Faraday effect.
