PT-symmetric optical structures represent a new generation of artificial optical systems which utilize gain and loss in a balanced fashion in order to perform a desired task. Such non-Hemitian arrangements exhibit interesting properties which are otherwise unattainable in passive Hermitian systems. As a result, since the first experimental demonstration of PT-symmetry in coupled optical configurations, there has been a flurry of activities in understanding and utilizing PT-symmetric processes in optics. Here we review recent developments in the newly emerging field of PT-symmetric optics.
