Paper Abstract

The influence of an external magnetic field on to the magneto-optical properties of media with a helical periodical structure is discussed. The case of light normal incidence is considered, and it is assumed that the external magnetic field is directed along medium axis. The transmission and reflection of the light incident normal onto a thin film having helical structure and being in external magnetic field is discussed. It is shown that at certain conditions this system can work as an ideal optical diode or one-sided reflector for polarized light. It is shown that when absorption is present in the system it becomes nonreciprosity for non-polarized light, i.e. a new type of nonreciprocity is appeared.
