New research : torsional photons realize multi-layer information loading
In the "Science Advances" journal recently published a report on the use of more information and communications technology to revitalize optical angular momentum. It is understood that this is a scientific team composed of British, German, New Zealand and Canadian physicists. By using information other than 0 and 1 to convey information, the application of “optical angular momentum” has reversed the problem of the propagation of optical communication in open space.
In the process of communication, traditional digital communication uses 0 and 1 to transfer information, and this experiment encodes twisted photons to allow them to pass additional information—similar to adding some letter information on a 0 and 1 basis. Scientists can "twist" photons (single light particles) in a way that is similar to a hologram applied to a credit card. Photons can have angular momentum and can carry this information to spread in free space.
It is understood that researchers have evaluated the feasibility of these quantum information transmission modes by testing the influence of the optical information carried by the phase and intensity of the optical angular momentum on the actual link in the urban environment. A 1600-meter-long link has been tested in Erlangen, Germany. The link passes through fields, streets and near high-rise buildings to simulate as accurately as possible the urban environment and atmospheric disturbances that may affect the transmission of information in space.
This study of the free-space optical system is a potential way to provide us with the bandwidth of the optical fiber without the need for a physical connection line. It is a high-dimensional free-space optics move towards a cheaper and more convenient alternative to buried fiber. The crucial step in the connection. However, the atmospheric disturbance in the experiment highlights the fragility of the wavefront phase shape for the broadband data transmission process, which also indicates that there is an urgent need for future adaptive optics.
