These reactions proceed efficiently under green light excitation and exhibit excellent enantioselectivities (up to 99% enantiomeric excess). Chiral 1,2-diamines are common structural motifs in ...

Over the years, several waveguides and structured materials have been developed to preserve linear and circular polarization over long distances and analyze these states with a sufficient degree of ...

Now, the "Ultrafast & Twisted Photonics" research group at the Max Planck Institute for the Science of Light (MPL) has developed a new hollow-core fiber that selectively guides optical vortices ...
