This is an oen access aricle disribued under he Creaive Commons Aribuion License, which ermis unresriced use, disribuion, and reroducion in any medium, rovided he original work is roerly cied. In his sudy, he eac raveling wave soluions of he ime fracional comle Ginzburg-Landau equaion wih he Kerr law and dual-ower law nonlineariy are sudied. The nonlinear fracional arial differenial equaions are convered o a nonlinear ordinary differenial equaion via a raveling wave ransformaion in he sense of conformae fracional derivaives. A range of soluions, which include hyerbolic funcion soluions, rigonomeric funcion soluions, and raional funcion soluions, is derived by uilizing he new eended ðg /GÞ-eansion mehod. y selecing aroriae arameers of he soluions, numerical simulaions are resened o elain furher he roagaion of oical ulses in oic fibers. 1. Inroducion The Ginzburg-Landau (GL) equaion [1 7] is one of he mos imoran arial differenial equaions in he field of mahemaics and hysics, which was inroduced ino he sudy of suerconduciviy henomenology heory in he h cenury by Ginzburg and Landau. The GL equaion usually describes he oical solion [8 15] roagaion hrough oical fibers over longer disances. Therefore, i is very imoran o analyze he dynamic behavior of he GL equaion. In aricular, searching for he aroimae analyical soluions or eac raveling soluions of he GL equaion has been more and more widely followed wih ineres because hey can hel o elain he comleiy of nonlinear oics. So, in recen years, many owerful mehods were used for finding he eac raveling soluions of he GL equaion, which include he firs inegral mehod [16], dynamical sysem mehod [17], ðg /GÞ-eansion mehod [18], iroa s mehod [19], and harmonic balance mehod []. In recen years, he fracional GL equaion [1 4] has been more and more widely followed wih ineres because i can be used o accuraely model some nonlinear oical henomena. In aricular, consrucing he eac raveling soluions of he fracional GL equaion is very imoran work because i can be beer elained he dynamics of solion roagaion hrough oical fibers over longer disances in nonlinear oics. So far, many imoran mehods have been roosed o find he eac soluions of he fracional GL equaion. In [5], Arshed eraced he hyerbolic, rigonomeric, and raional funcion soluions of he fracional GL equaion by he e ð ϕðξþþ-eansion mehod. In [6], Raza obained he eriodic and hyerbolic solion soluions of he conformae ime fracional GL equaion by using he soliary wave ansaz mehod and e ð φðχþþ-eansion mehod. In [7], Abdou e al. emloyed Jacobi s elliic funcion eansion aroach o rerieve douy eriodic funcion soluions for he ime-sace fracional GL equaion. In [8], Sirisubawee e al. invesigaed he cubic-quinic GL equaion by he modified Kudryashov mehod and ðg /G,1 /GÞ-eansion mehod. In [9], Ghanbari and Gómez- Aguilar obained he eriodic and hyerbolic solion soluions of he conformae GL equaion by using he generalized eonenial raional funcion mehod. Alhough eac raveling wave soluions of he fracional GL equaion have

The erms wih consans α and β arise from he erurbaion effecs. In aricular, γ comes from he deuning effec. a, b, α, β, and γ are real-valued consans. u is he comle conjugae numbers of u. Equaion (1) is used o model various hysical henomena, such as nonlinear waves, ose-einsein condensaion, second-order hase ransiions, suerconduciviy, suerfluidiy, liquid crysals, and srings.

Conclusion C 1 + # 1/n 1 e i ð k+w ð δ /δþ+θþ : C 1 ξ + C The ime fracional comle GL equaion wih he Kerr law and dual-ower law nonlineariy, which deics he dynamics of solion roagaion hrough oical fibers over longer disances, is sudied by using he eended ðg /GÞ-eansion mehod. A series of new eac soluions are consruced, including hyerbolic funcion soluions, rigonomeric funcion soluions, and raional funcion soluions. Comaring our resuls wih he soluions in he revious lieraure, we ge many new eac soluions. In order o furher undersand he dynamic behaviors of hese resuls, wih he hel of sofware Male 18, we have rovided some grahical reresenaion of he eac soluions of he ime fracional comle GL equaion wih he Kerr law and dual-ower law nonlineariy by seing he aroriae arameers. We believe ha he obained soluions may be of cardinal significance in he field of nonlinear oics. Moreover, in he aer, we have confirmed ha he eended ðg /GÞ-eansion mehod is owerful, reliae, and sysemaic, and hey could be alied for Conflics of Ineres The auhors declare ha here is no conflic of ineres regarding he uicaion of his aer.
