We study localized dissipative structures in a generalized Lugiato-Lefever equation, exhibiting normal group-velocity dispersion and anomalous quartic group-velocity dispersion. In the conservative system, this parameter-regime has proven to enable generalized dispersion Kerr solitons. Here, we demonstrate via numerical simulations that our dissipative system also exhibits equivalent localized states, including special molecule-like two-color bound states recently reported. We investigate their generation, characterize the observed steady-state solution, and analyze their propagation dynamics under perturbations.
我们研究了广义Lugiato-Lefever方程中的局域耗散结构，该方程表现出正常群速度色散和反常四次群速度色散。在保守系统中，这一参数区域已被证明能够产生广义色散克尔孤子。在此，我们通过数值模拟证明，我们的耗散系统也表现出等效的局域态，包括最近报道的特殊分子状双色束缚态。我们研究了它们的产生，表征了观测到的稳态解，并分析了它们在微扰下的传播动力学。
