A team of researchers has come up with a new way to discover linking light to the matter at the nanolevel. Experts have developed a tiny box from stacked atomically thin material, a type of feedback loop in which light and matter become one; thus opening up new possibilities in nanophotonics.
Photonics is involved in the technology of photodetectors and solar cells; photonic components being too small in size, are measured in nanometers, this process is called nanophotonics. Prospects that can be offered through nanophotonics is studied in fundamental research. The new study has developed a ‘lightbox’ which makes quick alternations between light and matter; it is through this swiftness that light and matter become one. Researchers combined two different concepts in an innovative way, which led to the discovery.
“We have created a hybrid consisting of equal parts of light and matter. The concept opens completely new doors in both fundamental research and applied nanophotonics and there is a great deal of scientific interest in this,” commented Ruggero Verre, a researcher in the Department of Physics at Chalmers. Verre is also one of the authors of the scientific article.
Reports suggest, the team also worked on nanoantennas that capture and amplify light effectively and also conducted research into a type of two-dimensional material known as TMDC material. It was this process of combining nanoantennas with two-dimensional material that created new possibilities for research.
The team used a popular TMDC material, tungsten disulfide, but they used it in a new way. Moreover, researchers created a tiny resonance box that made interactions between light and matter possible. Results of the resonance box concluded that the light captured in the box bounces round in a certain tone inside the material, this resulted in transferring light energy to electrons of the TMDC material. In other words, light energy oscillates between two states, light waves and matter, as long as it amplified and captured inside the box.
Since the team could successfully combine light and matter in a single particle with a diameter of only 100 nanometers or 0.00001 centimeters, this could induce futuristic fundamental research and cost-effective solutions in applied photonics.
A report on this discovery was recently published in Nature Nanotechnology.
