Abstract

We propose a new system of the dark–bright solitons conversion using a micro- and nano-ring resonators incorporating an optical add/drop filter, where the add/drop filter can be used to convert the dark soliton to bright soliton. The key advantage of the system is that the detection of the dark soliton pulse is normally difficult due to low level of input power. Firstly, a dark soliton pulse is input into a micro-ring resonator, then propagating into smaller micro- and nano-ring resonators. Secondly, the add/drop filter is applied (connected) into the ring system, where the bright and the dark solitons are obtained via the drop and through (or throughput) the ports of the add/drop filter, respectively. The results obtained have shown that the detected soliton power can be controlled by the input soliton power and the ring resonator coupling coefficient, which is enough to use in the transmission link. The optical and the quantum networks using dark soliton are also discussed.
