For First Time On-Chip Nanoantennas Enable High-Bit Rate Transmission

For First Time On-Chip Nanoantennas Enable High-Bit Rate Transmission

An international team of researchers led by a group at the Australian National University (ANU) is the first to demonstrate ultra-fast transmission of information through an optical nanoantenna that has been imprinted onto an optical waveguide. These results could have significant implications for telecommunication applications, enabling high-speed data transmission through these devices. Prior to this work, which is described in the journal Science Advances , there were very few examples in which an optical nanoantenna had been imprinted onto an optical waveguide. Additionally, those earlier examples had very limited functionalities, such as coupling light to a waveguide mode. “What we showed is that such an antenna of sub-micron size can sort and route different streams of information (encoded into the different polarizations of light) into different directions of the wa...
