Abstract

A nonreciprocal phase shift occurs in TM modes that travel in magneto-optic waveguides in which magnetization is aligned transverse to the light propagation direction in the film plane. The large nonreciprocal phase shift is obtained when a magneto-optic waveguide comprises a guiding layer with a high-refractive-index material. A magneto-optic waveguide with a Si guiding layer is obtained by depositing the Si layer on a magnetic garnet layer. An optical isolator employing a nonreciprocal phase shift is described which has the magneto-optic waveguide with the Si guiding layer. A laser diode integrated with the optical isolator can be developed by connecting the laser diode on the Si layer in the magneto-optic waveguide, which is a concept of garnet photonics.
