Summary: The interaction between optical solitons plays a crucial role in studying the interaction between light and matter, as well as the development of all-optical devices and the design of integrated optical paths. This study investigates the interaction of optical solitons based on the nonlinear Schrodinger equation, aiming to improve communication quality and system integration. By deriving solutions to the equation, the interaction of two solitons is analyzed, and suggestions are proposed to weaken their interactions.

Summary: This study investigates an extended (2+1)-dimensional perturbed nonlinear Schrodinger equation with Kerr law nonlinearity in a nano optical fiber. The inclusion of fourth-order spatial derivatives allows for the study of nonlinearity and spatial dispersion effects in the x and y directions. Optical soliton solutions of various types, such as bright solitons and dark solitons, are extracted using useful soliton ansatzes, demonstrating the capability of identifying exact solutions for nonlinear evolution equations in different fields.

Summary: This work investigates a two coupled nonlinear Schrodinger equation (CNLSE) applicable to high birefringence fibers. Various ansätze are used to derive bright and dark optical envelope soliton solutions, as well as solutions with distinct structures such as periodic, exponential, and singular. The analysis reveals the significant contribution of nonlinear terms to pulse compression feature and nonlinear birefringence phenomena.

Summary: A coupled nonlinear Schrodinger equation is used to describe the propagation of spatial-phase-modulated photovoltaic solitons and non-phase-modulated beams in a photovoltaic crystal. Through the use of Jacobian elliptic function solutions, the characteristics of these solitons in the long wave limit are determined by the Glass constants of the beams.

Summary: The study focused on the complex cubic-quintic Ginzburg-Landau equation and calculated the analytic one-soliton solution of the variable-coefficients CQGLE. It was found that rectangular dissipative soliton pulses of the variable-coefficients CQGLE can be effectively realized and controlled, breaking through the energy limitation of soliton pulses and potentially providing a theoretical basis for the preparation of high-energy soliton pulses in fiber lasers.

Summary: This paper investigates optical solitons in birefringent fiber by studying the (2+1)-dimensional generalized coupled nonlinear Schrodinger equation with the four-wave mixing (FWM) term. The study explores how the FWM parameter and some free parameters affect solitons' performance, as well as their energy transfer during elastic collision and separation. The conclusions drawn from this research may prove useful in improving communication quality in multi-mode fibers.

Summary: The experimental observations demonstrate the generation of domain-wall solitary pulses using a net anomalous dispersion Er-doped fiber ring laser without polarization-selective elements. By adjusting the pump power and polarization state appropriately, both bright and dark solitons can stably co-exist in the cavity. The use of a thulium-doped fiber as the saturable absorber enables the laser to exhibit good stability, which may have a significant impact on improving pulse-laser design and expanding practical applications in optical sensing, optical communication, and soliton multiplexed systems.

Summary: The study investigates symmetry-breaking and restoring bifurcations of solitons in a fractional Schrodinger equation, especially in the presence of CQ nonlinearity and a parity-time-symmetric potential. Solitons destabilize at the bifurcation point, but stability is restored through an inverse bifurcation in the case of CQ nonlinearity. Two mutually conjugate branches of ghost states are created in the presence of fractional diffraction.
