Optical fiber SELFOC* lens and lens array have widespread applications in coupling light sources to fibers, fibers to fibers, and fibers to detectors. The fiber SELFOC lens is characterized by the parabolic profile of index of refraction from the center to the edge of the fiber. This parabolic profile is generated by Cs or T(h) diffusions in the optical fibers. A liquid crystal lens and lens array will be described which have advantages of electric field controllable focal length, larger numerical aperture, thinner cell thickness, and ease in fabrication.
