Space-Division Multiplexing Workshop

28 June 2015 OSA Virtual Event

Internet traffic grows approximately 100 times every 10 years and the majority of the traffic is carried by single-mode fiber communication systems. However, the capacity that a single fiber can carry is reaching its theoretical limits due to the nonlinear shannon limit. The only option for continued capacity growth is to use additional spatial paths either in parallel single-mode fibers or through more integrated solutions such as fibers that have multiple cores, multiple modes, or both. In addition to these novel fibers, the success of space division multiplexing will depend on highly integrated and cost effective components that exploit multimode technology to simultaneously process the parallel data streams. Such components include switches, new fibers, amplifiers, filters, multi-mode and multi-core amplifiers, mode-converters.
Although space division multiplexing has potential to significantly reduce the cost and complexity of parallel systems, it also has its challenges. The closely packed spatial-paths can couple which causes crosstalk. The modes also have different losses and gains which cause mode dependent losses. Should this crosstalk be dealt with using advanced digital signal processing techniques, and what types of new components do we need to handle the mode dependencies? 
In recent years, outside of optical communications interest in multimode photonics research has been rapidly growing in quite disparate disciplines within optics, largely independently. With applications as diverse as searching for extra-solar planets to cutting sheet-metal. These research disciplines include biomedical imaging, astronomy, sensing, high-power amplifiers and quantum information science. Space-division multiplexing and these fields have very different applications but rely on many related techniques and suffer from many of the same technical challenges.
