Abstract

This paper presents a multi-soliton generation system for terabit data transmission. In this system, multi-solitons are produced by a series of micro-ring resonators (MRRs) incorporated with an add/drop filter. The generated multi-solitons are equalized by wavelength selective switch, therefore achieving flat frequency combs that can be used as multi-wavelengths for data transmission. The output signals from the MRRs, which have a soliton pulse range of 191.2–195.7 THz, result in 345 comb multi-wavelengths with specific FSR of 12.5 GHz. After the comb spectrum is split into odd and even carriers, 16-QAM is used to modulate each carrier with sinc-shaped Nyquist pulses. At this point, the modulation of neighboring carriers generates spectrally overlapping channels, which emulate orthogonal frequency division multiplexing. By applying 345 carriers, 16-QAM modulation, polarization multiplexing, and exploiting sinc-shaped Nyquist pulses with symbol rates of 12.5 GBd, a total data rate of 34.5 Tbit/s is achievable. The error vector magnitude and bit error rate of the system are also discussed.
