| 摘要 |
An optical gate array device which permits the use of an optical gate array with a pitch smaller than the diameter of optical fibers. The optical gate array has an array of optical gates, and an optical fiber array has an array of optical fibers. A lens is arranged between the optical gate array and the optical fiber array, for collectively achieving optical coupling between all of the optical gates of the optical gate array and all of the optical fibers of the optical fiber array.
