| description | An optical fiber with multiple openings made from the steps comprising fabricating an extrusion die using at least one additive manufacturing technique such that the extrusion die has a first set of plurality of channels that combine inside the die into a second set of plurality of channels with a different set of shapes and sizes, extruding a glass through the extrusion die, forming a fiber optic preform having a plurality of longitudinal openings that run the entire length of the fiber optic preform, attaching a barrier layer to the fiber optic preform to form a series of channels to which pressure can be applied by a gas, wherein each channel has a pressure that is independently controlled, and stretching the fiber optic preform at an elevated temperature into an optical fiber with multiple openings. |
