A photonic 'lab-on-a-chip'

Georgia Tech researchers have shrunk an optical device called wavelength demultipler (WD) by combining into one crystal three unique properties of photonics crystals. This optical discovery opens the way to sophisticated and cheap biosensors mounted on 'lab-on-a-chip' devices - sensors to run blood tests, detect chemicals in water supplies or for drug testing.
