Abstract
Misregistration and losses between the ends of coupled optical fibre-bundles are reduced by tapering the fibre ends. The ends are etched to remove a portion of the outer cladding glass around each glass core. The tapered ends are inserted into a low refractive index glass tube and drawn down in the tube to form a solid core glass zone. The solid end is polished to facilitate coupling to another bundle.
