“…The throughput output (E t1 ) shows localized ultra-short soliton signals (LOC and UOC) with an FSR of 90 GHz. The drop port output expressed by E t2 is shown in Figure 3(b), where multi-soliton signals could be generated [98][99][100][101]. Here, a high capacity of signals can be obtained by generating multi-soliton signals [102][103][104].…”

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.

“…The concept of an optical soliton has been a significant subject in many physical and engineering studies such as those of electronic telecommunication system and social media networks [1][2][3]. Optical solitons play a crucial role since they represent the nature of the propagation of pulse in various nonlinear media [4].…”

This paper seeks to find optical soliton solutions for Lakshmanan–Porsezian–Daniel (LPD) model with the parabolic law of nonlinearity. The spatiotemporal dispersion is included to the model, as it can contribute to handling the problem of internet bottleneck. This study was performed analytically using the traveling wave hypothesis to reduce the model to an integrable form. Then, the resulting equation was handled with two approaches, namely,the auxiliary equation method and the Bernoulli subordinary differential equation (sub-ODE) method. With an intentional focus on hyperbolic function solutions, abundant optical soliton waves including W-shaped, bright, dark, kink-dark, singular, kink, and antikink solitons were derived with the existing conditions. Furthermore, the behaviors of some optical solitons are illustrated. The spatiotemporal dispersion was found to significantly affect the pulse propagation dynamics. Finally, the modulation instability (MI) of the LPD model is explained in detail along with the extraction of the expression of MI gain.

“…The main performance characteristics of these resonators are the free-spectral range (FSR), the finesse (or Q-factor), the transmission at resonance, and the extinction ratio [3]. The major physical characteristics underlying these performance criteria are the size of the ring, the propagation loss, and the input and output coupling ratios (equivalent to the reflectivities of a Fabry-Perot resonator) [4]. On the other hand, strongly guiding ring waveguides with very large lateral refractive index contrast (airsemiconductor-air) can have diameters as small as 1-2 µm with negligible bending loss.…”

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.
