Filed: 1989-09-19
Abstract: PURPOSE:To obtain the optical coupling structure of a waveguide and a photodetector by cutting obliquely the waveguide of a vapor deposition part of a dielectric multilayer film at an angle for generating a total reflection by an end face of the waveguide. CONSTITUTION:In the part loaded with a photodetector of a waveguide 6, a dielectric multi- layer film 22 having a transmission characteristic of wavelength selectivity is formed by vapor deposition, and thereafter, the waveguide 6 is cut by a dicing saw so that an end face 23 of the waveguide 6 becomes about 45 deg.. Subsequently, a photodetector 14 is loaded and fixed on the dielectric multi-layer film 22 so that a light beam brought to total reflection by the waveguide end face 23 is coupled to the photodetecting surface. A signal light of wavelength lambda1 and light containing a crosstalk component of wavelength lambda2 are brought to total reflection by the waveguide end face 23 and made incident on the dielectric multi-layer 22, but in the dielectric multi-layer film 22, the crosstalk component of wavelength lambda2 is obstructed completely, only the signal light of wavelength lambda1 transmits through and coupled to the photodetecting surface of the photodetector 14, therefore, the photodetector 14 can photodetect only the signal of wavelength lambda1 having no crosstalk. In such a way, the optical coupling structure of the waveguide and the photodetector can be obtained at a low cost.

Filed: 1988-09-28
Abstract: PURPOSE:To form an SOI in excellent crystallizability with high precision by a method wherein a single crystal region formed on a slope of an oxide film is used as an active part of an element. CONSTITUTION:An oblique angle along the sidewall of a seed part, i.e., an opening part of an insulating film 22 is specified at a region. That is, a 110 facet is formed making an angle of 45 deg. with a 110 substrate so that, when the side of the insulating film makes an angle of 45 deg. with the 100 substrate while the 110 facet is being deposited along the sidewall of an oxide film, the 110 facet becomes perpendicular to the slope of the insulating film 22 to take the depositing direction of <100> on the perpendicular surface. When the side of insulating film 22 makes an angle not exceeding 45 deg. with the substrate 21, a component of the insulating film 22 is deposited outside in the <100> direction when the 110 facet is deposited stepwise so that any crystalline defects are apt to be developed with this effect notably added if the said angle falls below 40 deg.. On the other hand, even if the said angle exceeds 45 deg., the development of crystalline defects will not be affected so much.
