n a world first, scientists have stored light-based data as sound waves on a computer chip - a feat they compare to 'capturing lightning as thunder'.
Storing light as sound has been pursued by large companies such as IBM and Intel for years, but until now has never been achieved.
The researchers hope their breakthrough could lead to the creation of computers in which data can safely travel at the speed of light.
Researchers from the University of Sydney demonstrated the technological breakthrough in a new study, published in Nature Communications.
Transferring information from light to sound and back again inside a microchip is critical for the development of photonic integrated circuits – microchips that use light to manage data.
These chips are being developed for use in telecommunications, optical fibre networks and cloud computing data centres where traditional electronic devices are susceptible to electromagnetic interference, produce too much heat or use too much energy.
Dr Birgit Stiller, supervisor of the project, said: 'The information in our chip in acoustic form travels at a velocity five orders of magnitude slower than in the optical domain.
THE MICROCHIP
The researchers' chip is made of chalcogenide glass, which provides optimal guidance of both optical and acoustic waves.
The chip operates at room temperature and can be used with other computer components, which means it can be easily integrated into photonic circuits.
While light is an excellent carrier of data, its speed can become a nuisance inside computers.
To help overcome this issue, the researchers created an 'acoustic buffer' within the microchip, in which light was temporarily converted into sound.
