Original abstract

We investigate the effect of loss and gain on transmission characteristics of Kerr-nonlinear directional couplers. We consider a symmetric coupler made of two hybrid dielectric-plasmonic slot waveguides and introduce asymmetric gain profile. We classify the resulting steady states of the nonlinear system and demonstrate that asymmetric steady states, which can only occur for an asymmetric gain profile, cause strongly nonreciprocal transmission.

Czech abstract

Vyšetřujeme vliv zisku na spínací charakteristiky kerrovských nelineárních vazebních členů. Uvažujeme symetrický vazební člen tvořený dvěma hybridními dielektricko-plazmonickými štěrbinovými vlnovody s nesymetrickým profilem zisku. Klasifikujeme ustálené stavy nelineárního systému a ukazujeme, že nesymetrické stacionární stavy, které lze pozorovat pouze při nesymetrickém profilu zisku, způsobují silné nereciproké chování zkoumané struktury.
