Patent ID: 7409129

Claim:
An optical fiber array module comprising: a light emitting device to emit light having a pre-set divergence angle through a side surface thereof; an optical fiber array having a plurality of optical fibers; and a concentrator including a first side surface, a second side surface facing the side surface of the light emitting device, and a through-hole extended from the first side surface to the second side surface, wherein the through-hole has a width gradually narrower in a direction from the first side surface to the second side surface, wherein an end portion of the optical fiber array is inserted into the through-hole, thereby enabling concentration of the end portion of the optical fiber array; wherein the side surface of the light emitting device has a window; wherein the end portion of the optical fiber array is aligned with the window of the light emitting device at a distance there between to permit the end portion of the fiber array to be adhered to the window; and wherein the end portion of each of the optical fibers included in the optical fiber array is extended so that the end portion of the optical fiber array is gradually thinner, and an extension rate of the end portion is about 60 percent of the length of the end portion prior to being extended.
