Nonreciprocal transmission in coupled nonlinear waveguides with loss and gain

conference paper

English

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.
