Paper Abstract

In this paper is proposed a novel high spectral efficiency modulation scheme using time-squared pulses forming an orthogonal wavelength division multiplexing. Experimental results show a significant reduction of the interchannel linear crosstalk-induced penalty compared with Gaussian RZ modulation. Simulation studies are in good agreement with experimental results and show the system performance dependence on several multiplexing impairments inherent to this technique. The proposed modulation technique allows a maximum spectral efficiency of 1 bit/s/Hz without any other spectral efficiency enhancement technique like polarisation division multiplexing.
