Photonic Breakthrough Allows 'Lab-on-a-Chip'

Roland Piquepaille writes "Georgia Tech researchers have shrunk an optical device called wavelength demultiplier (WD) by combining into one crystal three unique properties of photonics crystals. This optical discovery opens the way to sophisticated and cheap bio-sensors mounted on 'lab-on-a-chip' devices -- sensors to run blood tests, detect chemicals in water supplies or for drug testing. Their new WD is less than a millimeter in all dimensions rather than the several centimeters of other currently available WDs. And it should not cost more to produce."

That's a "wavelength demultiplexer". It is wrong in the original article.

Demultiplexer not demultiplier

[coinreturn]

The error is in both the article summary and one place in the article. The proper term is "demultiplexer," not "demultiplier." A "demultiplier" is called a "divider."
