ABSTRACT:
An optical coupling module includes first, second, and third substrates, first and second optical fibers, and first and second lenses. The first substrate has a surface formed with a first V-groove. The second substrate has a surface formed with a second V-groove. The third substrate is arranged between the first and second substrates and has a surface formed with first and second recess. The first to third substrates have the surfaces flush with each other. The first and second optical fibers are fixed in the first and second grooves, respectively, and are arranged such that their end faces oppose each other. The first and second lenses are fixed in the first and second recesses, respectively, and are arranged on one optical axis of the first and second optical fibers to be spaced apart from each other by a predetermined distance.
