Researchers at PoliCom, Politecnico di Milano have presented the first experimental proof of an interferometric orbital angular momentum mode multiplexer/demultiplexer, exploiting a very compact configuration based on cylindrical lenses. 20-Gbit/s error-free transmission demonstrates the effectiveness of the proposed energy-saving all-optical passive demultiplexing technique, which is very promising for increasing the capacity in short-range optical links for data communications, where the power consumption is a fundamental issue.
