Spatial Division Multiplexing for Multiplex Coherent Anti-Stokes Raman Scattering

Journal of Lightwave Technology, 2023
We demonstrate how a narrowband pump and a broadband spectrum can be spatially multiplexed by selective coupling them in two distinct modes of a few-mode microstructure fiber. The first mode carries most of the input pump energy, and experiences spectral broadening.

Asynchronous spatial division multiplexing router [PDF]

Microprocessors and Microsystems, 2011
Asynchronous quasi-delay-insensitive (QDI) NoCs have several advantages over their clocked counterparts. Virtual channel (VC) is the most utilized flow control method in asynchronous routers but spatial division multiplexing (SDM) achieves better throughput performance for best-effort traffic than VC.
