| Abstract(in English) | An optical circulator is a nonreciprocal device which has an input/output transmission characteristic in a prescribed cyclic manner. The optical circulator is an important device for realizing highly functional photonic circuits. However, the optical circulator has not been realized yet on any semiconductor waveguide platform. In this study, we fabricate a silicon nanowire waveguide optical circulator employing a Mach-Zehnder interferometer configuration. The nonreciprocal function is provided by the nonreciprocal phase shift that is given by a magneto-optical garnet Ce:YIG directly bonded on the silicon waveguide. The 4-port circulator operation is successfully demonstrated with the highest forward-to-backward isolation of 15.3 dB at a wavelength of 1531 nm. |
