A proposed system of extremely narrow multisoliton pulse generation is presented. A PANDA system can be used to create signals in the form of chaotic noise inserted into an add/drop system. The capacity of the output signals can be improved by generation of multisoliton pulses with pulse width (FWHM) and free spectrum range (FSR) of picometres and picoseconds size. Multisoliton of dark and bright can be generated and propagated within the system. This system can be used to improve the scribing of the micro channels or the solar cell thin films. Using the ultra-short laser pulses, the micro channels with exact depths and well-defined outlines can be generated and fabricated without causing any damage to the ultra-thin-film solar cells. Results obtained show that controlling of the signals can be performed when the additional Gaussian laser pulse is used in the add port of the nonlinear system. In this work high capacity of narrow spatial and temporal multisoliton pulse with FWHM of 5 pm and 2.6 ps and FSR of 190 pm and 101 ps were simulated respectively where the central wavelength of the input power was selected to 1.55 m.

-This paper proposed a new idea of optical wireless communication simultaneously using the optical spin phenomena. The spin generation from bright and dark soliton conversion behaviors within a modified optical add-drop filter known as PANDA ring resonator is proposed. The orthogonal solitons can be formed within the system and detected simultaneously at the output ports. Under the resonant condition, the dark and bright soliton pair corresponding to the left-hand and right-hand rotating solitons (photons) can be generated. When a soliton is absorbed by an object, an angular momentum of either + ħ or -ħ is imparted to the object, in which two possible spin states known as optoelectronic(soliton) spins are exhibited. The arrays of orthogonal soliton spins can be applied a spin up for uplink and spin down for downlink representation in optical wireless communication.

In this paper, a microring resonator (MRR) system using double-series ring resonators is proposed to generate and investigate the Rabi oscillations. The system is made up of silicon-on-insulator and attached to bus waveguide which is used as propagation and oscillation medium. The scattering matrix method is employed to determine the output signal intensity which acts as the input source between two-level Rabi oscillation states, where the increase of Rabi oscillation frequency with time is obtained at the resonant state. The population probability of the excited state is higher and unstable at the optical resonant state due to the nonlinear spontaneous emission process. The enhanced spontaneous emission can be managed by the atom (photon) excitation, which can be useful for atomic related sensors and single-photon source applications.Optical microring resonator (MRR) has emerged as a potential photonic structure in integrated technology with low power consumption [1] . MRR contributes in various technological applications, such as optical sensors [2] , optical amplification [3] , polarization conversion [4] , optofluidic devices [5] , optical spin generators [6] , frequency shifters [7] and on-chip spectrometry bio-analysis [8] . In quantum, the interaction between atoms and electromagnetic field is described precisely by the energy state transition as interaction phenomenon occurs in small distance with short time.The probability of atom transition between two energy levels is used to explain the interaction between electromagnetic field and atoms. Based on the perturbation theory, the atomic state population remains constant, as the probability amplitude of an atom transiting to other energy states is small. However, in presence of strong light field, the atomic population increases in higher energy level [9] . The probability of atom transition is found in form of oscillation against time which shows that the atom could be in ground or higher energy level, and such oscillations are known as Rabi oscillation [10] . The energy states for a system can be analyzed using the Hamiltonian of time-dependent Schrodinger equation for the light-atom interaction.In this paper, a theoretical formulation for the optical bright soliton pulse propagation within the nonlinear silicon-on-insulator (SOI) double-series microring resonator (DSMRR) system is presented based on optical transfer function [11] and scattering matrix method [12] . The SOI shows the nonlinear optical properties at various wavelengths, which provides strong light confinement [13] and is suitable for high-speed passive-waveguide applications. The Rabi oscillation at the through port of DSMRR system is described by the Hamiltonian, which represents the atoms with ambient surrounding as an unperturbed condition and the atoms interacting with optical bright soliton beam as a perturbed condition. The Rabi frequency equations for the interaction between atom and light within the DSMRR system are obtained by the analytical derivation of two-level atom approxima...
