Data-transmitting light signal gets power boost from nanosized amplifier

Researchers from Aalto University and Université Paris-Sud have considerably upgraded the propagation of data inside a microchip.
Light is a more energy efficient way of transferring data than electricity because of its speed of travel but the rapid attenuation of light signals in microchips has prevented the use of light as a source of an information signal.

However, researchers at Aalto University have now invented a nanosized amplifier that is able to assist light signals to transmit through microchips. At the time of data is transferred inside a microchip signal attenuation can be significantly reduced according to the researchers, for example- from one processor to another. 

‘Photonics is at present widely used in internet connections and is increasingly being used by microcircuit systems because the light is a more energy efficient and speedy way of transferring data than electricity.

The researchers made their breakthrough with the help of a Finnish invention: the atomic layer deposition method. Using this method it is possible to process various kinds of microcircuits, as it plays an important role in manufacturing today's microprocessors.
As of today, the atomic layer deposition method has been used mainly in electronic applications. However, the newly released study indicates that possible applications also exist in photonics.

The study displayed that a light signal can be potentially boosted in various kinds of structures and that the structure of a microchip is not restricted to a specific type. The results indicate that atomic layer deposition is a promising method for developing microchip photonic processes.
