PURPOSE:To increase the optical coupling efficiency of the optical array link module which transmits plural light signals in parallel. CONSTITUTION:The optical array link module is equipped with a light emitting element array 30 where light emitting elements which each have high reflecting films 35 provided alternately on its front projection surface and rear projection surface are arrayed, a 1st fiber array 51 which has optical fibers 51-1 arrayed at a pitch twice as large as the array pitch of the light emitting elements and is arranged on the front surface side of the light emitting element array 30, a 1st lens array 41 which is installed between the light emitting element array 30 and 1st fiber array 51 and constituted by arraying lenses 41-1 at a pitch twice as large as the array pitch of the light emitting element, a 2nd fiber array 52 which has optical fibers 52-1 arrayed at a pitch twice as large as the array pitch of the light emitting elements and is arranged on the rear surface side of the light emitting element array 30, and a 2nd lens array 42 which is installed between the light emitting element array 30 and 2nd fiber array 52 and constituted by arraying lenses 42-1 at a pitch twice as large as the array pitch of the light emitting elements. |
