Young's Double Slit Plus Plasmonics (IMAGE) Brown University Caption Young's double slits with micrometer distances can make incoherent light coherent and vice versa. Surface plasmon polaritons (SPPs) excited at each slit can be used to mix the random fluctuations of the incident electromagnetic fields at the two slit locations.
