Orbital angular momentum (OAM) presents a promising degree of freedom for enhancing data transmission in optical communications. By utilising the helical phase front of light beams, OAM offers a ...

a.The architecture of the all-optical CNN for OAM-mediated machine learning, which can be applied to encode a data-specific image into OAM states. The photonic neural network comprises a trainable ...

A researcher has developed a new technique using light which could revolutionize non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the ...

In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to Earth using light. But in order for the signals to reach all the way and not ...

Figure 1: NICT's 7.4 km, 2 Tbit/s horizontal propagation experiment (April 2025). The ST terminal was used as the transmitter and the FX terminal as the receiver. The terminals exchanged pseudo-random ...
