Paper Abstract

A numerical study of the propagation in Kerr nonlinear prism and grating couplers is presented based on singularity expansions for the field coefficients. The numerical results show that the change of location of pole and zeros in the complex plane explain the bistable behaviour of the prism-coupler and that an analytic description of the hysteresis loops can be obtained. It is also found that the grating coupler is a more complex case but that the relative position of pole and zeros does not change when the guide index is changed, allowing to define a scalar dynamic detuning parameter.
