The light was 'bent'

Australian National University scientists have for the first time successfully bent a small beam of light on a two-dimensional plane, paving the way for the production of chips that interact with cheaper and faster light, Physorg said. good.

This is the world's first two-way demonstration work of scientific beams called 'Airy beam' .

The team came from many countries, including three members of the School of Physics and Engineering Studies at the Australian National University (ANU), which gave a small beam of light running on a flat plane crawling over an object. block, and then bend it back in the right direction on the plane, the other side of the obstacle.

For the first time scientists have successfully demonstrated the theory of bending light on a two-dimensional plane.

'Science students are often taught that light rays move along straight lines and they cannot pass through curved angles ,' said team member Professor Yuri Kivshar, ANU University.

Recently, it was discovered that small beams of light could be bent in the laboratory, much less a common beam of light. Those beams of light were named Airy Beams, after the English astronomer George Biddell Airy famous for studying light in the rainbow.

'Our team has demonstrated that these light beams can also be bundled on the flat surface of a chip. We have also observed a very interesting characteristic of these beams that is the self-returning phenomenon, ie light waves can return to the right path after they have crawled across the surface. obstructed ' , Physorg continues to explain Professor Kivshar.

Dr Dragomir Neshev, another member of the research team, said the experiment helped open up potential for many areas.'This discovery gives momentum to many useful feasible applications, especially in the field of communication technology. This discovery also opens up the potential for processing biological molecules in a cheaper way than it is now. '

Recently, many research groups around the world have competed to prove the topic of two-dimensional plane bending, especially the groups in the United States, China and Korea.
