Spatial division multiplexing for optical data center networks [PDF]

2018 International Conference on Optical Network Design and Modeling (ONDM), 2018
Emerging mobile and cloud applications drive ever-increasing capacity demands, particularly for short-reach optical communications, where low-cost and low-power solutions are highly required. Spatial division multiplexing (SDM) techniques provide a promising way to scale up the lane count per fiber, while reducing the number of fiber connections and ...

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.
