Abstract
Bistable or multistable transmissions are classically the result of the introduction of nonlinear layers into a resonant Fabry-Perot cavity. A single inhomogeneous film, with a periodic lateral structure, can also give rise to a bistable transmission for significant intensity ranges, due to Fano resonances, a strong frequency-dependent transparency variation related to the transfer via guided modes. A self-consistent simulation tool which allows for the computation of multivalued transmission is developed and the peculiar shape of the hysteresis loops associated with Fano resonances is studied.
