## What is/are Dark Bright Soliton?

Dark Bright Soliton - Dark soliton solution, dark-bright soliton solution, hyperbolic function solution and trigonometric function solution of the (3+1) dimensional KZK equation and (3+1)-dimensional JM equation have been found by using this method.^{[1]}Dark, bright and dark-bright soliton solutions of this equation are procured.

^{[2]}Dark solitons, singular solitons, combo bright-singular solitons, combo singular solitons, the combination of combo singular solitons and bright solitons and the combination of combo dark-bright solitons and singular solitons have been found.

^{[3]}We investigate dark-bright soliton dynamics in a coupled nonlinear Schrodinger equation in presence of complex potentials and the associated spectral problem.

^{[4]}Interestingly, in both driving scenarios, dark-bright solitons are nucleated in the absence of correlations.

^{[5]}The new results are elliptic, hyperbolic, trigonometric, rational type which are representing to solitary waves, periodic waves, traveling waves, kink-antikink solitons, dark-bright solitons.

^{[6]}As applications, the solutions of the interaction between a dark-bright soliton and a rogue wave (RW), the solutions of the interaction between two dark-bright solitons and a second-order rogue wave, the solutions of the eye-shaped rogue wave and triangle rogue wave are obtained.

^{[7]}Here, TaSe2 deposited on D-shaped fiber is used as saturable absorber (SA) in Er-doped fiber laser, and four switchable operating states (bright solitons, dark solitons, bright-dark soliton pairs and their HML counterparts, as well as bright-dark-bright soliton pairs) are realized successfully.

^{[8]}Specially, the angles between propagation directions of dark-bright solitons(breathers) and the positive direction of x-axis are analysed on the basis of free parameters.

^{[9]}All established closed-form wave solutions include special functional parameter solutions, as well as hyperbolic trigonometric function solutions, trigonometric function solutions, dark-bright solitons, bell-shaped profiles, periodic oscillating wave profiles, combo solitons, singular solitons, wave-wave interaction profiles, and various dynamical wave structures, which we present for the first time in this research.

^{[10]}On the plane wave background, the first-order bright and dark-bright solitons are obtained.

^{[11]}These closed-form invariant solutions are successfully presented in the form of distinct complex wave-structures of solutions like combo-form solitons, dark-bright solitons, W-shaped solitons, the interaction between multiple solitons, parabolic wave solitons, multi-wave structures, and curved-shaped parabolic solitons.

^{[12]}Many new travelling wave solutions, such as mixed dark-bright soliton, exponential and complex domain, are reported.

^{[13]}These two efficient methods are applied to extracting solitary wave solutions, dark-bright solitons, singular solitons, combo singular solitons, periodic wave solutions, singular bell-shaped solitons, kink-shaped solitons, and rational form solutions.

^{[14]}Moreover, trigonometric, complex, strain conditions and dark-bright soliton wave distributions are also reported.
