Abstract: An optical fiber end securing structure and a method of securing an optical fiber end are introduced. The optical fiber end securing structure includes a stub component, a substrate and an adhesive component. The stub component is cylindrical. The stub component has axially a through hole for receiving an optical fiber. The substrate has a securing groove. Two walls of the securing groove extend in the axial direction of the stub component. The distance between the two walls is less than the diameter of the stub component in the radial direction. The outer circumferential surface of the stub component is in linear contact with apexes of the two walls. The adhesive component fills the securing groove and connects the securing groove and the stub component. Therefore, the optical fiber end securing structure and the method of securing an optical fiber end enable the optical fiber to undergo high-precision engagement.
