| 英文摘要 | A semiconductor laser and an optical waveguide of an optical coupler, formed on a substrate are optically coupled with each other by aligning their positions horizontally by using a plurality of laser elements and cores for the laser and the waveguide respectively and arranging them in an array respectively so that a difference between their pitches is less than double of tolerance tolerated for optically coupling with each other, the waveguide having partially a composite core composed of: a main core; a sub core surrounding the main core and having a refractive index lower than that of the main core; and a cladding layer surrounding the sub core and having a refractive index lower than that of the sub core. |
