Abstract

A classical 3-port optical circulator is demonstrated on the silicon-on-insulator platform. A garnet die with a
magneto-optical Ce:YIG layer is bonded on top of a Mach-Zehnder interferometer circuit using a thin adhesive
bonding layer. The power transmission between different ports is characterized in the presence of an external
magnetic field, transversal to the light propagation direction. An isolation of 22dB is measured at a wavelength
of 1562nm.
