Abstract
Methods of forming a total-internal-reflection (TIR) optical fiber lens are disclosed. The methods include heating an end of an optical fiber with a defocused infrared laser beam to form a bulbous tip having a curved outer surface that defines a lens surface. The bulbous tip is laser cleaved to define a TIR facet. Light traveling in the fiber diverges at an effective fiber end and is reflected by the TIR facet through the lens surface to form an image at an image plane.
