The inverse Faraday effect (IFE) generates magnetic fields by optical excitation only. Since its discovery in the 60 s, it was believed that only circular polarizations could magnetize matter this magneto-optical phenomenon. Here, we demonstrate generation of an IFE via a linear polarization light. This new physical concept results from local manipulation light plasmonic nano-antenna.

In this paper, we numerically demonstrate that an actively controllable electromagnetic induced transparency (EIT) behavior can be obtained in a hybrid terahertz metamaterial. A unit cell of the metamaterial consists metallic split-ring resonator surrounded by concentric graphene close-ring resonator, serving as superradiant and subradiant modes, respectively. The EIT-like effect results from destructive interference caused strong near field coupling between mode resonators. classical...

Light–matter interactions are often considered governed by the electric optical field only, leaving aside magnetic component of light. However, part plays a determining role in many processes, from light and chiral-matter photon-avalanching to forbidden photochemistry, making manipulation processes extremely relevant. Here, creating standing wave using metallic nanomirror, we manipulate spatial distributions fields their associated local densities states, allowing selective control...

Abstract Fourier domain optical coherence tomography (FD-OCT) is a well-established imaging technique that provides high-resolution internal structure images of an object at fast speed. Modern FD-OCT systems typically operate speeds 40,000–100,000 A-scans/s, but are priced least tens thousands pounds. In this study, we demonstrate line-field (LF-FD-OCT) system achieves OCT speed 100,000 A-scan/s hardware cost We the potential LF-FD-OCT for biomedical and industrial applications such as...
