Paper Abstract

We propose a novel system for generating multiplexed dark-soliton pulses using multiple light sources via an optical multiplexer, whereby dark solitons with different center wavelengths can be generated. The multiplexed signals can be transmitted into the communication link and filtered by using an optical add-drop filter. By using suitable simulation parameters, we have shown that dark solitons with different center wavelengths can in fact be obtained. In application, the communication capacity can be increased by using the multiplexed dark solitons; moreover, the transmission signals can be secured by utilizing the behavior of dark solitons. A free spectrum range (FSR) 2.5 nm and an amplified power of 30 W of dark solitons with wavelength 1.60 µm can be achieved. Channel spacing of the communication signals within a wavelength router can be provided by using a suitable FSR, which can be managed by using crosstalk effect analysis.
