OPTICAL INTEGRATED CIRCUIT PACKAGE AND ITS ASSEMBLY METHOD

摘要

PURPOSE:To provide an optical integrated circuit package which is an optical integrated circuit constituted to optically couple a semiconductor light emitting element and optical fibers via an optical integrated circuit substrate, stably and easily executes the optical coupling and does not generate a change in the output light of the optical fibers even in long-term use and an assembly method therefor. CONSTITUTION:The optical integrated circuit substrate 1 is fixed at the center in the package 3 previously provided with through-holes 4 at side walls in order to stably and easily optically couple an LD 10 and the optical fiber 2b via an optical waveguide. A stem 13 mounted with the LD 10 and a spherical lens 11 for coupling and a ferrule supporting member 15 holding and fixing two pieces of the optical fibers 2b for emission are installed into the through-holes 4 on the side walls of the package 3. The stem 13 and the ferrule supporting member 15 are positionally adjusted and fixed in such a manner that the optical axes of the LD 10 and the optical fibers 2b are aligned via the optical waveguide. As a result, the optical coupling of the LD 10 and the optical fibers 2b is stably and easily executed. Mispositioning does not arise and always the stable output light is obtd. in spite of the long-term use.
