ABSTRACT:
A fiber optical connector microlens is provided with a self-aligning optical fiber cavity. The microlens includes a convex first lens surface and a second lens surface. A fiber alignment cavity is integrally formed with the second lens surface to accept an optical fiber core. A lens body is interposed between the first and second lens surfaces, having a cross-sectional area with a lens center axis, and the fiber alignment cavity is aligned with the lens center axis. In a first aspect, the fiber alignment cavity penetrates the lens second surface. In a second aspect, an integrally formed cradle with a cradle surface extends from the lens second surface, and a channel is formed in the cradle surface, with a center axis aligned with the lens center axis. The fiber alignment cavity includes a bridge covering a portion of the channel.
