摘要：

We propose a design of TE mode magneto-optical (MO) circulator based on the asymmetric slot waveguide with the multimode interference (MMI) principle. The nonreciprocal phase shift (NRPS) of two high-order TE modes in the MO waveguide lead to different phase difference between them when light propagates in the opposite direction. In-plane asymmetric structure makes the device to work in TE polarization. The crosstalk is less than 50 dB with 1.75 dB insertion loss at the wavelength of 1550 nm. A 14 nm broadband device design based on this structure is demonstrated, which shows insertion loss below 3 dB and crosstalk less than 20 dB.
