Abstract:
1. An optical fiber microlens that has a core and cladding and at the tip an anamorphic means of convergence, in which at the optical fiber tip that faces the light source or radiated beam a first pair of inclined surfaces is formed in a positional relationship such that they intersect in a wedge shape, on the axis of a plane perpendicular to the axis of the optical fiber along the center of the core are formed second inclined surfaces at the angle θ to a plane perpendicular to the central axis of the optical fiber and lengthwise to the wedge-shaped tip, and wherein the tip of the optical fiber microlens is processed as a curved surface, in which the intersection of the curved surface with each of two perpendicular planes that contain the central axis of the core is an arc, each with a specified radius.
