LIGHT RECEIVING COMPOSITE PARTS FOR OPTICAL COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide all-purpose light-receiving parts for optical communication having excellent incident efficiency of signal light and little connection loss and to provide a low-cost and high-quality receiver which permits popularization of optical communication. SOLUTION: The light-receiving composite parts for optical communication have such a structure that a connector having a soft light-transmitting material attached to the passage of light in the connecting parts is integrated with a light-receiving device to form a tightly adhered structure between the light entering face of the light-receiving device and the soft light-transmitting material. The light transmitting body has 1.30 to 1.60 refractive index and <=60 degrees hardness according to JIS (type D). The light guide of the light receiving device is sealed with a transparent material (having 1.30 to 1.60 refractive index and <=70 degrees hardness according to JIS (type A)). The light transmitting material and the transparent sealing material consist of one kind selected from a silicone resin, acrylic resin, epoxy resin, elastomer resin and derivatives of these resins.
