PROVIDENCE, R.I. [Brown University] -- Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. In a paper published in the ...

In the famous double-slit experiment, an interference pattern consisting of dark and bright bands emerges when a beam of light hits two narrow slits. The same effect has also been seen with particles ...

Researchers have developed and demonstrated a method for changing the spatial coherence of light. In a paper, the researchers show that they can use surface plasmon polaritons—propagating ...
