Optical solutions of Biswas–Arshed equation in optical fibers

This paper studies the Biswas–Arshed model that compensates for the group velocity dispersion (GVD) by the dispersion of time and space. When the GVD and non-linearity are very small, the propagation patterns of the model are given by the complete discriminant system for polynomial method. Based on the results, under the specific parameters, we analyze the soliton transmission dynamic.

Chirp-free optical dromions for the presence of higher order spatio-temporal dispersions and absence of self-phase modulation in birefringent fibers

In this paper, we study Biswas–Arshed (BA) model in birefringent fibers for chirp-free solitons (dromions) with the aid of sub-ordinary differential equations (ODE) method. The BA model studies the soliton transmission in optical fiber. We obtain bright, periodic, and Weierstrass elliptic function solutions with constraint conditions.

The Physical Parameters of EDFA and SOA Optical Amplifiers and Bit Sequence Variations Based Optical Pulse Generators Impact on the Performance of Soliton Transmission Systems

This study has outlined the effects of physical parameters of erbium doped fiber amplifier (EDFA), semiconductor optical amplifier (SOA) on the performance of amplified soliton transmission systems. Injection current-based SOA, EDFA length is taken into account. It is observed that the optimum soliton power and signal per noise ratio are achieved with 5 m EDFA length and 900 mA injection current-based SOA. As well as the bit sequence variations based user defined bit sequence generator are employed in order to measure the soliton transmission system performance. The signal per noise ratio is enhanced with 4 bit sequence. Soliton peak power, output soliton power, and maximum Q-factor are optimized with 8 bit sequence for soliton propagation length of 150 km and possible transmission data rates of 160 Gb/s. Improvement percentage ratio in soliton peak power by using two amplification techniques a long propagation length is deeply stimulated with optiwave simulation program.
