A novel high-spectral-efficiency modulation scheme using square time pulses in orthogonal wavelength-division multiplexing is proposed. Experimental results demonstrate the significant reduction of the interchannel linear crosstalk-induced penalty compared with Gaussian return-to-zero (RZ) modulation. The proposed technique allows a maximum spectral efficiency of 1 b/s/Hz. Simulation studies and experimental work confirming the expected performance are presented.

    • ...In the last years, orthogonal-WDM (OWDM) modulation has been proposed in the DWDM system to meet the demand of increased transmission capacity [5], and OWDM using coherent detection with channel spacing equal to the symbol rate is demonstrated [6]...
    • ...Once the spectrum is sinc-shaped, the different channels are orthogonally multiplexed [5]...
    • ...Noise reduction by spectrum shaping requires the interference from a given DWDM channel over the adjacent channels to be moved from the central frequency of the interfered channels to the side areas of these channels [5]...
