Abstract:The transmission and reflection of electromagnetic guided waves by a periodic structure with a delocalized intensity-dependent nonlinearity was studied using a semianalytical approach. We show that such a nonlocal nonlinear distributed feedback grating can exhibit bistable and switching behaviors depending upon the input intensity and the detuning.
