Design and analysis of new lensed-fiber for laser to fiber coupling

A new lensed-fiber with two different rods of a spherical end is proposed. The lens geometry and refractive index are changed to obtain various working distance and spot size. A lensed-fiber with high coupling efficiency (/spl sim/50%) and long working distance (>100 um) is demonstrated.
