In 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.
