摘要：

In this work, we analytically find that perfect waveguide mode conversion could be realized in a waveguide structure with zero index metamaterials (ZIMs) by constructing air grooves inside ZIMs. Such a result is not only obtained in a straight waveguide, but may. extend to bending or even multi-port waveguide systems. The proposed ZIM waveguides could also simultaneously work as optical diodes, which can effectively achieve unidirectional transmission. All phenomena are well verified by numerical simulations.
