Abstract:

 The use of fiber optic cable in support of the enormous bandwidth expansion has become the gold standard for communications.

Not only does optical fiber offer tremendous bandwidth, it is also low in attenuation, small in cross section, inexpensive, impervious to electromagnetic interference, and there are significant economies of scale on components developed for the myriad of optical communications markets (long haul, fiber to the home, metro networks, etc.). Short haul requirements continue to grow and are expected to exceed the capacity of simple single mode fiber transmission. Spatial multiplexing is a new technique in fiber communications allowing fiber capacity to grow in another dimension by carrying signals on orthogonal modes of light.  The short length and high capacity requirements for data center and fronthaul links make them well suited for exploitation of orbital angular momentum (OAM) of light in spatial multiplexing.
