Recently, the manipulation of the spin angular momentum (SAM)—or polarization—of these attosecond pulses has been extensively explored [1] - [3] . In particular, circularly polarized attosecond pulses ...

As fast as modern electronics have become, they could be much faster if their operations were based on light, rather than ...
