Abstract

We demonstrate that the interplay of a magneto-optical layer sandwiched between two judiciously balanced gain and loss layers which are both birefringent with misaligned in-plane anisotropy, induces unidirectional electromagnetic modes. Embedding one such optically active non-reciprocal unit between a pair of birefringent Bragg reflectors, results in an exceptionally strong asymmetry in light transmission. Remarkably, such asymmetry persists regardless of the incident light polarization. This photonic architecture may be used as the building block for chip-scale non-reciprocal devices such as optical isolators and circulators.

  5. There are several ways to address the problem with absorption. One approach is to replace a uniform magnetic material with a slow-wave magneto-photonic structure [6]. Under certain conditions, such a structure can enhance asymmetric transmitance effects associated with magnetism, while significantly reducing absorption. The problem with the above approach is that it does not apply to infrared and optical frequencies it can only work at MW frequencies. Another approach is to incorporate gain and loss together with non-linearity [19]. In this case, however, optical isolation occurs only for specific power ranges.
