We discuss a new and generic scheme for such devices. The basic configuration comprises an asymmetric resonator within an active or passive nonlinear medium. This arrangement enables all-optical flip-flop operation and switching with a reduced threshold. In addition, a novel optical isolator concept based on resonator asymmetries is is introduced. The model is also applicable to photonic crystal based resonators UR - https://www.ksp.kit.edu/9783866441507 UR - https://directory.doabooks.org/handle/20.500.12854/54760 ER -
