摘要	We theoretically report the influence of a class of near-parity-time-(PT-) symmetric potentials on solitons in the complex Ginzburg-Landau (CGL) equation. Although the linear spectral problem with the potentials does not admit entirely-real spectra due to the existence of spectral filtering parameter alpha(2) or nonlinear gain-loss coefficient beta(2), we do find stable exact solitons in the second quadrant of the (alpha(2),beta(2)) space including on the corresponding axes. Other fascinating properties associated with the solitons are also examined, such as the interactions and energy flux. Moreover, we study the excitations of nonlinear modes by considering adiabatic changes of parameters in a generalized CGL model. These results are useful for the related experimental designs and applications. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
