“…The nonlinear pulse propagation and the generation of parabolic pulses in dispersion decreasing fiber (DDF) have been described in [30][31][32][33]. MI in DDF was analyzed using the GNLSE by Xu et al [34], where the authors have consider the femtosecond pulse propagation and studied the MI behavior under various cases.…”

A theoretical study of modulational instability (MI) in the semiconductor doped dispersion decreasing fiber (SD-DDF) is presented. We consider the combination of saturation of nonlinear response and the dispersion decreasing fiber (DDF). The exact dispersion relation is calculated by means of linear stability analysis. Different fiber systems are considered alongside the proposed SD-DDF for insight and to offer the cutting edge of the proposed model over the others. The two extreme physical effects considered lead to an exciting outcome, where decreasing dispersion leads to broadening the spectral width and saturation, on the other hand, suppresses the MI gain and the bandwidth. A bandwidth relation between different fiber systems is presented, and the idea can open the design of a fiber structure with desired dispersion profile by a suitable manipulation of these effects. We propose that instead of using DDF whose bandwidth is limited by the manufacturing constraints, the use of SD-DDF offers better tailoring of the bandwidth profile by suitably altering the saturation parameter. Thus we emphasize that the proposed SD-DDF will be a feature prospect for wide range of applications, especially in the context of ultrashort pulse generation using MI.

Reliable data transmission capacity is a crucial factor in supporting high-data-rate communication for smart cities by implementing the Internet of Things. Optical fiber has become the most favorable transmission media by taking advantage of optical signals. However, when optical signals propagate through optical fibers, disturbances occur as the transmission distance increases. These disturbances affect the system performance indicated by the deteriorating transmission data quality in terms of the quality factor (Q-factor) and bit error rate. These parameters are vulnerable to certain factors that can alter signal transmissions such as fiber attenuation, group velocity dispersion (GVD), and self-phase modulation (SPM) as a nonlinear effect. In this study, the effects of these factors on a single-channel, single-mode fiber are investigated using a bit rate of 10 Gbps at various transmission distances and source power levels. The parametric study of attenuation, GVD, and SPM with non-return-to-zero (NRZ) modulation format are considered at various transmission distances, from 10 to 100 km, and input powers of 5 and 10 dBm are simulated using OptiSystem to characterize the parameters of Q-factor and received power. The results indicate that the performance of the system deteriorates as the transmission distance increases, and the dominant effect that impacts the performance is GVD. This result is useful for designing effective and precise fiber optic transmission for high-data-rate transmission.
