“…where A and z are the amplitude of optical field and propagation distance, respectively, L D is the dispersion length of the soliton signal [61,62], and the carrier frequency of the signal is ω 0 . The soliton signal keeps its temporal and spatial width invariance while it propagates; therefore, it is called a temporal and spatial soliton [63][64][65]. A balance should be achieved between the dispersion length (L D ) and the nonlinear length (L NL =1/Γφ NL ) [66][67][68].…”

In this work optical solitons carrier generation in a nonlinear waveguide microring resonator (MRR) is simulated and presented. Therefore, a system comprises of a W-band (75 to 110 GHz) optical millimeter wave generation using a Panda microring resonator (PMRR) is presented. A bright soliton with a central frequency of 50 GHz and power of 1 W is introduced into the PMRR. The optical Kerr effect manifests itself temporally as self-phase modulation, a self-induced phase- and frequency-shift of a pulse of light as it travels through a medium. Large bandwidth within the microring device can be generated by using a soliton spectrum input into the nonlinear PMRR. The 90 GHz free spectral range (FSR) solitonic signals were simply generated by adjusting the system parameters. By beating the closely center frequencies of the solitonic signals, we can obtain a center frequency which corresponds to that spacing as millimeter wave used for many applications in signal processing and communications such as wireless cable systems and indoor–outdoor communication.

“…A trapping force is produced via the add port signals that constitute the input powers; thus the optical soliton are generated and controlled within the half-panda ring resonator. The input intensity powers, particularly in the add port of the system, are the key parameters allowing significant manipulation of the optical soliton, and this control over light intensity and velocity is a highly attractive feature for medical applications [25].…”

Interferometric measurement techniques have been employed in research and industry for investigations into propagation behavior aspects of the optical solitons within semiconductor lasers. The half-PANDA ring resonator system introduced in this paper consists of an add/drop multiplex connected to a microring resonator on the right side, where the output powers can be controlled by specific parameters. The collision of dark and bright solitons occurs inside the system in which femtosecond (fs) optical solitons with 100 MHz repetition rate form the through and drop port outputs of the system. A trapping force is produced via the add port signals that constitute the input powers; thus the femtosecond optical soliton are generated and controlled within the half-PANDA ring resonator. The results of the soliton signals are obtained based on the iterative method technique in which a number of experimental and practical parameters are employed. These circumstances allow for manipulation of the trapping bandwidth by means of system parameter alterations. The input powers of the dark and bright solitons are 5.12 mW and 4 mW respectively. The full width at half maximum (FWHM) of the through and drop port output signals are 35 and 76 femtoseconds respectively correspond to 0.76 and 1.56 terahertz (THz) in frequency domain, where the repetition rate of the solitons is 100 MHz.

Multi-optical solitonic carriers suitable for use in optical communication systems and telecommunications have been generated via microring resonators (MRRs) incorporating an add/drop filter system. The generated multi solitonic carriers utilizing the MRRs were sufficiently stable for transmitting in a free space channel while experiencing very low dispersion during propagation. Moreover, the technique used which is iterative method using MRRs allowed for greater number of channels as multi-channel generation that could be utilized in a wavelength division multiplexing (WDM) system. Solitonic carriers were created, with each carrier possessing a free spectral range (FSR) of 12.45 GHz and a full width at half maximum (FWHM) of 250 MHz.
