‘Strange effect’ raises possibility of smaller, smarter
optical filters

Polarization, in sync. On the macro, everyday level,
it reads as an oxymoron. To the University of Nebraska–Lincoln’s
Xia Hong and her fellow nanoscientists, though, the apparent
contradiction makes a kind of harmonious sense. And it might just
spur the development of smaller, more versatile optical filters
that are especially adept at playing with a trick of the
light.
