Abstract

Disclosed is an optocoupler structure wherein force whereby an optical fiber end face is pressed upon a lens is sustained. The disclosed optocoupler structure is configured of a lens body and a clamp. The lens body comprises a lens unit, further comprising a lens, and an anchoring unit. The anchoring unit further comprises an optical fiber guide wherein the optical axis of an optical fiber is positioned when the optical fiber is imposed thereupon. The clamp further comprises a positioning unit, a pressure spring, and a retaining unit. The positioning unit positions the clamp, excluding the direction of the optical axis of the optical fiber. The pressure spring makes contact with the end face of the optical fiber and the face of the lens body that matches the direction of the normal, and generates recoil when the clamp moves in the opposite direction to the direction of the normal of the face of the lens. The retaining unit is formed in a component of the clamp that presses the optical fiber, and retains such that the optical fiber does not move in a direction away from the lens.

Description

technical field [0001] The present invention relates to an optical coupling configuration for optically coupling a lens and an optical fiber and a method of assembling the optical coupling configuration. Background technique [0002] As a technique for optically coupling a lens and an optical fiber, there is a method of using an adhesive. As one of such techniques, there is a technique described in Patent Document 1, for example. In the technique described in Patent Document 1, optical fibers are aligned using a pressure plate to a lens component (lens + guide groove), and fixed with an adhesive. In addition, FIG. 1 is FIG. 1 of Patent Document 1, Figure 1A is a perspective view of an optical coupler shown in Patent Document 1, Figure 1B It is a sectional view of the optical coupler shown in patent document 1. 1A is an optical coupler, 2A is a lens component, 3A is a lens forming part, 4A is a fiber holding part, 5A is a collimator lens, 6A is a fiber guide groove, 7 is...
