Design and System Benefits of Integrated Multi-Core Wavelength-Selective Switch

Strong mixing in mode division multiplexed fiber reduces group delay spread, mode dependent loss (MDL), and accumulated nonlinearity. Previously we demonstrated that it also broadens the passband of cascaded few-mode WSS passages. Here we analyze the performance of multi-core WSSs, and the favorable impact of strong coupling for MC-WSS cascades.
