The invention discloses a fully-polarized light isolator. The fully-polarized light isolator realizes a fully-polarized blocking effect based on a non-Eermitus system designed by combining anisotropic gain loss with a Faraday effect. The method can be realized by combining a single-layer thin film with polarization performance with multiple layers of dielectric materials, magneto-optical materials and metal structures with gains. According to the method, the novel full-polarized light isolator based on the non-Hermi system can be obtained, and the isolator has the advantages that the number of needed optical elements is small, energy loss is low, even negative loss (gain) is achieved, and the isolation effect is good.
