“…By using the bright soliton input signal, the operation can be successfully achieved by dark-bright soliton conversion within microring resonator, which can be used to represent optical logic NOT gate (optical switching). This dark-bright soliton conversion can be controlled, where the high-security communication in long distance using such concept has been reported and confirmed [29,30]. The simulation shows that the ultrafast-optical switching time of ( =0.14 ps), an on-off ratio of ~47.99 and propagation time of ~0.30 ps are obtained.…”

A dark-bright soliton conversion is used to perform the two arithmetic logic unit(ALU) operations namely adder and subtractor operations. The advantage of the system such as power stability, non-dispersion and the dark-bright soliton phase conversion control can be obtained. The input source into the circuit is the bright soliton pulse, with the pulse width of 35 ps, the peak power at 1.55 µm is 1 mW. By using the dark-bright soliton conversion pair, the generated logic bits can be controlled, and the secure bits can be achieved. The simulation results show the output signal with a minimum loss of only 0.1% with respect to a low input power of 1 mW, and ultra-fast response time of about 0.30 ps can be achieved. It gives the ultra-high bandwidth of more than 40 Gbits-1. The circuit composes 6 microring resonators made of InGaAsP/InP material with smaller ring radii of 1.5 µm, and the total physical scale of the circuit less than 100 2 .

“…For the soliton pulse in the micro ring device, a balance should be achieved between the dispersion length (L D ) and the nonlinear length (L NL = (1/ NL ) [46], where  = n 2 ×k 0 , is the length scale over which disperse or nonlinear effects makes the beam becomes wider or narrower [47][48][49][50]. For a soliton pulse, there is a balance between dispersion and nonlinear lengths, hence L D =L NL [51][52][53].…”

The microring resonator (MRR) system can be used to trap optical solitons. These types of pulses are used to generate entangled photon required for quantum keys. The required information can be provided via the quantum keys. We simulate localized spatial and temporal soliton pulses to form an optical communication used in wireless systems. The input soliton pulses with peak power of 500 and 550 mW are used to generate a spectrum of chaotic signals within the nonlinear medium, where the nonlinear refractive index is selected to n 2 =2.2 x 10-17 m 2 /W. The ultra-short soliton pulse can be trapped within the 3.52 GHz frequency, where the temporal soliton pulse with FWHM of 25 ps could be simulated and used to generate entangled photon pair. The generated entangled photons are input into a wireless router system which is used to transfer them within a network communication system. The router system is used to receive the information and convert it to analog signals at the end of the transmission link, thus data can be sent to the users via a secured optical communication system using MRRs.
