Abstract: Achieving exact balance between spatially separated gain and loss is generally regarded as a necessary condition for parity–time (PT)-symmetric optical systems [1]-[12]. We introduce generalized PT (gPT)-symmetric optical structures, which have an asymmetric and unbalanced… read more here.
