Automatic alignment for splicing of non-circular fiber

Abstract

A method of aligning a non-circular fiber with another component is provided. A method of aligning a first D-fiber with a second D-fiber includes rotating the first D-fiber; obtaining a first image profile of an end of the first D-fiber; using the first image profile to measure a diameter of a cladding of the first D-fiber along a first direction; and repeating these operations until a minimum diameter of the cladding of the first D-fiber is aligned along the first direction. The method also includes rotating the second D-fiber; obtaining a second image profile of an end of the second D-fiber; using the second image profile to measure a diameter of a cladding of the second D-fiber along the first direction; and repeating these operations until a minimum diameter of the cladding of the second D-fiber is aligned along the first direction.
