Water acts as a 'light switch' on photonic circuits

Using water to “write” light, scientists have designed a photonic circuit inside a photonic crystal that combines several optical elements. As the optical equivalent of an electronic circuit, this design marks another step on the path to realizing all-optical devices for communication and IT applications.
