Abstract

Abstract In this paper, we present non-reciprocal transmission in a composite PT-asymmetric ternary system consisting of two magneto-optical structures with opposite magnetic fields. Two schemes to realize PT-symmetry breaking are proposed to realize abnormal transmission in asymmetric multilayers with small gain/loss factors. One method is to adjust the parameter of magnetic fields applied on the magnetic-optical layers, and the other method is to adjust positions of gain and loss layers. The PT-symmetry breaking system can realize the abnormal and non-reciprocal transmission with small gain/loss factors with more practical applications in integrated photonics, communications and other fields.
