In our latest publication, we determine the optimal bidirectional orthogonal communication channels through arbitrary and scattering optical systems using photonic processors. The processors consist of meshes of electrically tuneable Mach–Zehnder interferometers in silicon photonics. The meshes can configure themselves based on simple power maximization or minimization algorithms without external calculations or calibration or any prior knowledge of the optical system.
Our findings offer potential for applications in multimode optical communication systems, promising efficient channel identification, adaptability to dynamic media, and robustness against environmental challenges.
