Abstract
A collimator array includes a substrate; a plurality of lenses formed on one face of the substrate; and a plurality of projecting parts, each of which is formed on a portion corresponding to the lens on the other face of the substrate, respectively and is fusion-connected to an optical fiber, respectively; wherein an area of the fusion-connected face of the projecting part with respect to the optical fiber is set to be larger than a cross sectional area of the optical fiber. Thereby, it is possible to provide a collimator having fewer variations in an output beam angle and a diameter of an output beam and having excellent strength, and a method for manufacturing the same.
