The modern world is surrounded by endless electronic devices and its mountains of cables and load accessories.
However, for people living in remote or regional environments, telecommunications infrastructure can face hard obstacles Upon reaching these most isolated areas.
However, researchers at the University of Ottawa have been developing a new laser energy converter that can transmit electricity to remote destinations to long distances, even in the toughest environments.
Devices can currently get out of the power over fiber systems. These systems involve a fiber optic cable that converts optical power into electrical energy.
“In the traditional power over fiber systems, most of the laser light is lost,” says Professor Karin Hinzer at the University of Ottawa. PluscuasOne of the main Canda Solar Research facilities.
This can restrict the length of fiber optic cables, which can be a problem for remote locations in extreme environmental conditions.
“With these new devices, the fiber can be much longer.”
In collaboration with the Fraunhofer Institute for Solar Energy Systems in Germany, Sunlab researchers created a simulation model for photonic energy converters in infrared wavelengths used for telecommunications.
Fotonic power converters are devices that convert laser light into electrical energy through a fiber optic cable.
“The manufactured device shows a dramatic improvement in the transmission of power and data in longer distances than a kilometer, where traditional systems are not viable,” says the first author of The Paper, Gavin Forcade.
The key to his findings was to use multibunction converters. These converters stack multiple unions of semiconductors one on top of each other.
A semiconductor union is the limit from which a positively loaded and negatively loaded semiconductor meets. This union controls the electricity flow, absorbs laser light and turns it into electrical energy.
Using the multijunction design, the research equipment could produce 2 volts of electricity at its maximum point with more than 53% efficiency.
In previous studiesFotonic power converters with a single layer have achieved an efficiency of up to 52.8% but have only produced 0.6 volts.
While the team hopes that these developments can help lead to more reliable telecommunications networks, they also believe there could be other benefits.
“This could improve power to high voltage and monitoring sensors for smart networks without the risk of ray failures,” says Hinzer.
“It could reduce the risks of sparks in dangerous environments and could transmit power and data simultaneously to remote devices in existing fiber optic infrastructure.”
Researchers also say that this technology could have more applications in space that feeds things such as drones, satellites and lunar vehicles.
The developments of the Sunlab team and their colleagues are published in the magazine Physical Sciences cell reports.
