Abstract
A method is described that involves scanning a laser beam across and applying a stretching force to a fusion region that is formed by a neighboring pair of optical fibers that include a core and a cladding layer. The scanning and applying occurs while the optical permissiveness of an optical path that flows through the fusion region is monitored.
