Impact of optical phase conjugation on the nonlinear Shannon limit

Ellis, A.D.; Al Khateeb, M.A.Z. and McCarthy, M.E. (2017). Impact of optical phase conjugation on the nonlinear Shannon limit. Journal of Lightwave Technology, 35 (4), pp. 792-798.


Compensation of the detrimental impacts of nonlinearity on long-haul wavelength division multiplexed system performance is discussed, and the difference between transmitter, receiver and in-line compensation analyzed. We demonstrate that ideal compensation of nonlinear noise could result in an increase in the signal-to-noise ratio (measured in dB) of 50%, and that reaches may be more than doubled for higher order modulation formats. The influence of parametric noise amplification is discussed in detail, showing how increased numbers of optical phase conjugators may further increase the received signal-tonoise ratio. Finally the impact of practical real world system imperfections, such as polarization mode dispersion, are outlined.
