A novel system of multisoliton generation using nonlinear equations of the propagating signals is presented.This system uses a PANDA ring resonator incorporated with an add/drop filter system.Using resonant conditions,the intense optical fields known as multisolitons can be generated and propagated within a Kerr-type nonlinear medium.The present simulation results show that multisolitons can be controlled by using additional Gaussian pulses input into the add port of the PANDA system.For the soliton pulse in the microring device,a balance should be achieved between dispersion and nonlinear lengths.Chaotic output signals from the PANDA ring resonator are input into the add/drop filter system.Chaotic signals can be filtered by using the add/drop filter system,in which multi dark and bright solitons can be generated.In this work multi dark and bright solitons with an FWHM and an FSR of 425pm and 1.145nm are generated,respectively,where the Gaussian pulse with a central wavelength of 1.55 μm and power of 600mW is input into the system.The generation of multisolitons becomes an interesting subject when it is used to enlarge the capacity of communication channels.[1] The high optical output of the ring resonator system is of benefit to long distance communication links.[2] Two techniques can be used to generate soliton pulses.First,soliton pulses can be obtained using a ring resonator system where large amplified signals are achieved.Second,a Gaussian soliton can be generated in a simple system arrangement.[3]This application becomes an attractive tool in the area of photonics for soliton generation and investigation.
