Abstract
The method for forming a tip of an array optical fiber disclosed is one in which an etching resistive material such as a photoresist is applied first on an end portion of a coated material covering constituent fibers of the array optical fiber, and then the ends of the constituent fibers are etched. Due to the presence of the etching resistive material, the etching solution does not dissolve the coated material. In an alternative method, the etching resistive material such as a photoresist is applied on a side surface of a tip portion of each constituent fiber of the array optical fiber exposed from the coated material, the tip portion is cut and flattened together with the etching resistive material, and the end faces of the constituent optical fibers are etched. The presence of the etching resistive material prevents the tip diameter of the constituent optical fiber from becoming small.
