Synthesizing an implementation framework for responsible research and innovation

The concept of Responsible Research & Innovation (RRI) seems to gain initial momentum. The lack of collective meaning however, results in a plethora of publications, which describe RRI from ad hoc perspectives. To provide a robust foundation for scholars and practitioners seeking to implement RRI, we aim to integrate those perspectives...

Fully controlled photonic spin in highly confined optical field

As an intrinsic attribute of light, the spin angular momentum (SAM) of photons has aroused considerable attention because of the fascinating properties emerging from light–matter interactions. We show that a diffraction-limited focal field with a steerable photonic spin structure in three dimensions can be produced under a 4π microscopic...
