ABSTRACT:
An optical fiber module comprises a light-emitting chip based on a semiconductor substrate, a vertical cavity surface emitting laser formed on a primary plane of the light-emitting chip, a guiding hole opened on a secondary plane of the light-emitting chip, and an optical fiber stuck to the secondary plane of the light-emitting chip. The position of the guiding hole is aligned to that of the surface emitting laser, and the guiding hole is close to the surface emitting laser. By inserting a tip of the optical fiber into the guiding hole, the optical fiber is coupled optically to the surface emitting laser only with mechanical positioning. The light-emitting chip is mounted on an electronic circuit board with the primary plane attached to it. Since the optical fiber is taken out from a secondary plane of the light-emitting chip, the assembly of the optical fiber module is simply done by coupling an optical fiber to the light-emitting chip after the light-emitting chip is attached to the electronic circuit board bonded on a package.
