Compensation of nonlinear effects in optical communication systems through phase-conjugation

This work demonstrates that the use of the mid-nonlinearity temporal inversion (MNTI) technique could allow the realization of efficient transmission systems at ultra-high bit rates, leading to a significant impact on the design, assessment, and implementation of future transmission links. In particular, this technique could open the way to the low cost upgrade of standard low bit-rate systems to 10Gb/s or multi-level, phase-modulated systems.
