摘要： PROBLEM TO BE SOLVED: To miniaturize an optical module using a lens by making the angle of at least one end face of each optical fiber different from that of the end face of the other optical fiber. SOLUTION: As for this optical fiber part 10, the tip 12 of a two-core capillary 11 holding two optical fibers 13 and 14 is ground so that the angle of the tip of either optical fiber 13 may be different from that of the other optical fiber 14. By such structure, the lens need not be provided in every optical fiber and optical signals of two optical fibers are connected to other optical fiber by one lens. In such a case, as for the angle of grinding, grinding is performed so that the emitting or the incident angle of a light beam may be a desired angle, and relation between the grinding angle and the angle of the emitted light beam is decided according to the refractive index of the optical fiber and that of an incident or an emitting side Thus, the external size necessarily required in the case of assembling the optical module in a device can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To suppress deterioration in insertion loss when a heat-shrinkable tube is mounted on an optical waveguide type module. SOLUTION: When the heat-shrinkable tube is mounted on the optical waveguide module constituted by connecting and fixing an optical fiber block having at least one optical fiber arrayed and fixed on a substrate on both sides of an optical waveguide chip so that the optical axes are aligned, the internal temperature of the heat-shrinkable tube is held lower than at least the glass transition temperature of an adhesive at the time of the shrinkage of the heat-shrinkable tube and the maximum internal temperature of the heat- shrinkable tube after the heating is held lower than the glass dislocation temperature of the adhesive to suppress the deterioration in insertion loss. Further, the heat-shrinkable tube after shrinking by being heated is forcibly cooled at least partially to suppress a rise in the temperature after the heating.
