Abstract: PURPOSE: An optical subassembly and a fabrication method thereof are provided to achieve the optical subassembly of small size, to simplify the coupling between an optical fiber and an optical device, and to reducing the production cost. CONSTITUTION: An optical module consists of a mold housing(11), a silicon optical bench(12), a bedplate(13), and a printed circuit board(14). The mold housing is aligned with the silicon bench by inserting a guide plate(25,26) of the mold housing into a guide groove(18,15) of the silicon bench. A case(22) of the mold housing and the printed circuit board is sealed with epoxy. An optical fiber(28) is inserted in a crenated gap(17) of a V-shaped groove(16) of the silicon optical bench via an optical fiber inserting opening(29) and the guide groove. The optical fiber is compressed by a push plate(24) of the mold housing, thereby being tightly contacted in the V-shaped groove. Therefore, the optical fiber is aligned by only the V-shaped groove of the silicon bench. The inserted optical fiber is firmly fixed by sealing the optical fiber inserting opening with epoxy. In the hand alignment method of the optical device and the optical fiber using the silicon optical bench, a die bonding pad or a flip chip bonding pad is used for attaching the optical device, an alignment mark is used as a mate alignment means relative to the V-shaped groove.
