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.

Fiber optic connector microlens with self-aligning optical fiber cavity

A fiber optical connector microlens is provided with a focal plane aligning fiber trap. The microlens is made from a convex first lens surface, a second lens surface (planar or convex), and a fiber trap integrally formed with the second lens surface for aligning a face of an optical fiber core in a microlens focal plane. In one aspect, the fiber trap includes a barrel attached to the second lens surface and a clamping mechanism to prevent an inserted fiber core, with a diameter about equal to a barrel interior surface diameter, from being withdrawn from the barrel. The fiber trap clamping mechanism can be an irregular barrel interior surface to frictionally engage a fiber core exterior surface, a constricted region of the barrel interior surface, having a diameter smaller than an uncompressed fiber core diameter, or a corkscrew region of the barrel interior surface.
