磁光隔离器被证明与硅波导使用。该隔离器是基于马赫-曾德尔干涉仪采用非互易相移，并通过将磁光石榴石CeY 2Fe 5 O 12（Ce：YIG）直接键合到Si波导上制成。表面活化键合基于在高真空室中的氧等离子体暴露。通过施加外磁场观察到非互易相移。在1559 nm波长处获得了21 dB的隔离比。(C)2008年美国物理学会。
A magneto-optical isolator is demonstrated for use with a Si waveguide. The isolator is based on a Mach-Zehnder interferometer employing a nonreciprocal phase shift and is fabricated by bonding a magneto-optic garnet CeY2Fe5O12 (Ce:YIG) directly onto the Si waveguide. The surface-activated bonding is based on oxygen-plasma exposure in a high-vacuum chamber. The nonreciprocal phase shift is observed by applying an external magnetic field. An isolation ratio of 21 dB is obtained at a wavelength of 1559 nm. (C) 2008 American Institute of Physics.
