Abstract
Wavelength-selective switches (WSSs) are the key wavelength-routing components in optical meshed networks. We discuss possible architectures for WSSs that support multimode fibers, and related tread-offs between key switch characteristics like spectral passband, number of switching ports, and insertion loss. We also present experimental results for WSSs that support few-mode fibers with 3 spatial modes.
