Researchers are developing topological insulators that could one day enable efficient light-based computation


Photonic materials are those that emit, detect or manipulate light. These materials play a crucial role in various sectors such as telecommunications, data processing and storage, and solar cells. Due to their wide use, there is a continuing need to make them effective. Researchers at the University of Central Florida (UCF) are developing new photonic materials that could one day enable superfast light-based computing. Known as topological insulators, the single materials are like wires that have been twisted, meaning they carry current outward while the interiors are insulated.

The researchers believe that topological insulators are important because they could be used in circuit designs with more processing power without generating heat. This would remove a big problem in today’s devices – overheating.

The UCF researchers published their findings in the journal Natural materials. In the study, they detailed a new approach to creating the materials, using chained honeycomb lattice design.

The researchers said the new photonic materials they developed overcome the drawbacks of contemporary topological designs, providing more functionality and control. It also minimizes power losses. They confirmed their findings using advanced imaging techniques and numerical simulations.

The group hopes their design will lead to a departure from traditional modulation techniques, bringing light-based computing closer to reality.

“Bimorphic topological insulators introduce a new paradigm shift in photonic circuit design by enabling secure transport of light packets with minimal losses,” said Georgios Pyrialakos, postdoctoral researcher at UCF and lead author of the study. , in a press release.

The researchers added that topological insulators could enable the use of faster photonic computers that consume less power and could also one day lead to quantum computing, allowing for hundreds of millions of times more processing power. faster than current computers.

The development of new photonic materials plays a vital role in the growth of information technology in the 21st century.
