Abstract

Low connection loss and high operation efficiency are realized by decreasing the waveguide cross section of a light control portion that is a part of an optical waveguide and relatively increasing the spot size of the guided light beam at the light control portion. The dimensions of a light input portion (22), the light control portion (24), and a light output portion (26) meet the single mode conditions. At least, the relationship among the widths W1, W2, and W3 of the light input portion (22), the light control portion (24), and the light output portion (26) is expressed by inequalities W2<W1, and W2<W3, and the relationship among the thickensses T1, T2, and T3 of the light input portion (22), the light control portion (24), and the light output portion (26) is expressed by inequalities T2<T1, and T2<T3.
