The fabrication and experimental results on the performance of a planar silica lens pair that facilitates low-loss optical beam propagation in free space between opposing planar silica waveguides/singlemode fibres are presented. Each lens uses the parabolic graded refractive index vertically and the convex curvature horizontally to focus the optical beam in free space. The lens pair, designed for...
A new scheme for the fabrication of collimate lens for single mode fiber have been developed using liquid droplet of UV cured resin. A small amount of liquid resin is placed on the output surface of single mode fiber to form a collimate lens. The output beam from the fiber through this lens is monitored with a wave-front sensor. The centering error of the fiber position to the ferrule is adjusted...
