| 英文摘要 | PURPOSE:To reduce the degree of freedoms of aligning and to facilitate it by forming a diffraction grating in which a period is specified in a semiconductor light source or an optical waveguide, and so adhering the surfaces of the semiconductor light source and the optical waveguide that the propagating directions of both the lights substantially coincide. CONSTITUTION:A diffraction grating 200 is provided on a P-type InGaAsP contact layer 5 in a window 9a formed at the electrode 9 of a semiconductor light source 100, adhered to an optical waveguide, and the part of the light is thereby introduced into the optical waveguide via the diffraction grating. When the equivalent refractive index of the light source 100 is n1 and the equivalent refractive index of the optical waveguide is n2, the period A of the diffraction grating 200 satisfies ALPHA=Nlambda/¦n1+ or -n2¦. In order to adhere the light source 100 to the waveguide, the light source 100 is inverted upside down, so placed on a board 11 that the propagating directions of both the lights coincide, so ally adjusted that the emitting light from the waveguide becomes maximum, and the electrode 9 is adhered to an electrode 13 by heating. Thus, the coupling is performed only by aligning in a plane. |
