Modulation formats for multi-core fiber transmission [PDF]
Optics Express, 2014 ©2014 Optical Society of America We investigate high dimensional modulation formats for multi-core fibers (MCFs) and spatial superchannels. We show that the low skew variations between MCF cores maybe exploited to generate 'multi-core' formats that offer
