摘要：
An interferometric optical isolator that employed a nonreciprocal phase shift was studied. The nonreciprocal phase shifts in magneto-optic waveguides were calculated at a wavelength of 1.55 mu m. The magneto-optic waveguides included a CeY(2)Fe(5)O(12) (Ce:YIG) layer as either a guiding layer or a cladding layer. When the Ce:YIG layer was used as a cladding layer, the nonreciprocal phase shift had its maximum with a high-refractive index guiding layer. The magneto-optic waveguide with SiO(2)/Si/Ce:YIG structure is a practical and promising candidate for a nonreciprocal phase shifter in the interferometric optical isolator. (C) 2008 Elsevier B.V.
