Figure 3: Experimental and theoretical results of multiplexing/demultiplexing of four OAM beams. Figure 4: Experimental results of 16-QAM signals over pol-muxed OAM ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220004 considers high frame-rate orbital-angular-momentum multiplexing holography. The development of mobile Internet, especially ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

When a magnetic material like nickel is zapped with an incredibly short laser pulse, it loses its magnetism almost instantly within femtoseconds, or a millionth of a billionth of a second. But physics ...
