Index Modulation for Spectral Efficiency Improvement in Multicore Fibers
Using index modulation in 37-core fiber, we show 11% improvement in spectral efficiency with seven-core excitation and MIMO-free DSP by encoding additional bits through modulating on/off status of specific core combinations with minimal crosstalk.
