We analyze the intensity-dependent optical response of the passive optical limiters realized with distributed-feedback structures, which consist of alternating layers of materials possessing opposite Kerr nonlinearities. By elaborating an analytical model and employing numerical simulations, we explore device performance with respect to key requirements for passive optical-limiter deployment. We prove that the proposed limiting mechanism results in complete clamping of transmitted intensity to a sensor-safe limiting value, independent of incident intensity. We provide a direct analytical result of this limiting intensity in terms of structural and material parameters.
