Abstract
A novel technique is provided, which can manufacture an optical nonreciprocal element constituted of an Si waveguide layer and a magneto-optical material layer without using wafer bonding. A magneto-optical material layer is deposited on a substrate, an Si layer is deposited on the aforesaid magneto-optical material layer, a waveguide is formed on the aforesaid Si layer, and the aforesaid magneto-optical material layer is magnetized so as to be able to cause a light propagating in the aforesaid waveguide to generate a nonreciprocal phase change.
