An ultra-degree-of-freedom structured vector beam

Optics Express recently published research demonstrating a laser that is able to produce a new type of vector beam. This so-called vector-ray-wave beam with 5 degrees of freedom breaks the paradigm of the conventional vector ...

High-order synthetic dimensions in waveguide photonic lattices

In physics, a very intuitive way of describing the evolution of a system proceeds via the specification of functions of the spatiotemporal coordinates. Yet, there often exist other degrees of freedom in terms of which the ...

Shedding light on untapped information in photons

Conventional optical imaging systems today largely limit themselves to the measurement of light intensity, providing two-dimensional renderings of three-dimensional scenes and ignoring significant amounts of additional information ...

Magnetic charge crystals imaged in artificial spin ice

A team of scientists has reported direct visualization of magnetic charge crystallization in an artificial spin ice material, a first in the study of a relatively new class of frustrated artificial magnetic materials-by-design ...
