This paper addresses solitons in nonlinear directional couplers in non-Kerr law media, with spatio-temporal dispersion. Both twin-core couplers as well as multiple-core couplers are studied. The nonlinearities studied are Kerr law, power law, parabolic law, dual-power law and log law. Bright, dark and singular soliton solutions of the governing equation are studied.

具有时空色散的非线性定向耦合器中的光孤子

本文讨论了非克尔定律介质中非线性定向耦合器中的孤子，具有时空色散。研究了双芯耦合器和多芯耦合器。研究的非线性是克尔定律、幂律、抛物线、双幂律和对数定律。研究了控制方程的亮、暗和奇异孤子解。
