Programmable photonics for free space optics communications and computing

Establish multiple and robust communication channels through arbitrary complex optical media is demonstrated by using integrated photonic processors based on meshes of Mach-Zehnder interferometers. The receiver is capable of compensating for scintillation induced by atmospheric turbulence automatically, without any need of knowledge of the link. The processor is able to performs a physical Singular Value Decomposition operation and any other algebraic operation.
