Photo-coupling device

Abstract

Abstract PURPOSE:To contrive to make a photo-coupling device small and light by integrating an optical fiber, a photo semiconductor element and an electronic circuit element by a system wherein a block having a V-groove and an insulating substrate are combined together. CONSTITUTION:A photo semiconductor chip 14 is fixed on the surface of an insulating substrate 11 and applied metallization 12 for wire-bonding. A V-groove 16 is formed in a block 13 having the V-groove 16 with a diamond cutter and mounted on the substrate 11 to combine the block 13 with the substrate 11, and the semiconductor chip 14 is adapted to be fitted thereinto in the form of insertion, and positioning the semiconductor chip 14 is automatically carried out. In succession, an optical-fiber 15 is fitted and secured in the V-groove 16. In this case, the optical- fiber 15 and the semiconductor chip 14 are determined of positions through the common V-groove 16 and the optical axis is automatically adjusted, so that the fine adjustment is not required. Whereby small parts such as sleeve and neutron applied machining in high precision become unnecessary, the assembling process is made simple and the device can be make small and light.
