Abstract
A method of fabricating a multi-element fiber scanner includes providing a fiber optic cable having a cladding region and a fiber core and focusing a laser beam at a series of predetermined locations inside the cladding region of the fiber optic cable. The method also includes creating a plurality of damage sites at the predetermined locations, exposing the fiber optic cable to an etchant solution, and preferentially etching the plurality of damage sites to form a base having a base plane and a longitudinal axis orthogonal to the base plane, a retention collar disposed a predetermined distance along the longitudinal axis from the base, a first fiber link including the fiber core, passing through the base plane, and joined to the retention collar, and a plurality of additional links joined to the base, extending from the base to the retention collar, and joined to the retention collar.
