114Gbit/s soliton train generation through Raman self-scattering of a dual frequency beat-signal in dispersion decreasing optical fibre
Chernikov, S.V., Richardson, D.J., Laming, R.I., Dianov, E.M. and Payne, D.N. (1993) 114Gbit/s soliton train generation through Raman self-scattering of a dual frequency beat-signal in dispersion decreasing optical fibre. Applied Physics Letters, 63, (3), 293-295. (doi:10.1063/1.110082).
We report the generation of 114 Gbit/s trains of 250 fs fundamental solitons. The pulses are generated due to the conversion of an intense optical beat signal (generated from two DFB laser diodes and an erbium doped fiber amplifier combination) into a soliton train due to nonlinear propagation in a 1.6 km fiber of steadily decreasing dispersion. The train repetition rate corresponds to the beat frequency of the input signal and was readily tunable between 80 and 120 GHz. The results of a computer simulation of the system are found to be in good qualitative agreement with the experimental observations.
