Programmable integrated Photonics for space division (de)multiplexing

InP and Silicon Photonics integrated optical devices able to mux and demux signals encoded on different orthogonal modes. They operate on 2 and 4 channels at 10 Gbit/s with less than −15 dB residual crosstalk. Transparent photodetectors, realized though the non-invasive ContacLess Integrated Photonic Probe (CLIPP) technology are exploited to assist the (de)mux configuration.
